Dear colleagues,

Please find enclosed a corrected EVN Call for proposals. The previous message contained
in particular a mistake related to RadioAstron. The correct section should be:

     RadioAstron Observations
     ------------------------

   * Proposals requesting the EVN as ground array support for RadioAstron
     proposals for the AO3 period (1 July 2015 - 30 June 2016) should be
     submitted at this deadline.

My apologies,
Michael

              **************************************************
                             European VLBI Network
                               Call for Proposals
                            Deadline 1st February 2015
              **************************************************


                This text is also available on the web at
                http://www.oso.chalmers.se/evn/call.txt


     Observing proposals are invited for the EVN, a VLBI network of radio
     telescopes spread throughout Europe and beyond, operated by an
     international consortium of institutes (http://www.evlbi.org/).

     The observations may be conducted with disk recording (standard EVN)
     or in real-time (e-VLBI).

     The EVN facility is open to all astronomers. Use of the Network by
     astronomers not specialised in the VLBI technique is encouraged.

     The Joint Institute for VLBI in Europe (JIVE) can provide support and
     advice on project preparation, scheduling, correlation and analysis.
     See EVN User Support at http://www.jive.nl.


     Future Standard EVN Observing Sessions (disk recording)
     -------------------------------------------------------
     2015 Session 2 May 28 - Jun 18 18/21cm, 6cm ...
     2015 Session 3 Oct 15 - Nov 05 18/21cm, 6cm ...
     2016 Session 1 Feb 26 - Mar 19 18/21cm, 6cm ...

     Proposals received by 1st February 2015 will be considered for
     scheduling in Session 2, 2015 or later. Finalisation of the planned
     observing wavelengths will depend on proposal pressure.
     The dates for Session 1 2016 are as yet provisional.


     Future e-VLBI Observing Sessions (real-time correlation)
     -------------------------------------------------------
     2015 Mar 24 - Mar 25 (start at 13 UTC) 18/21cm, 6cm, 5cm or 1.3cm
     2015 Apr 14 - Apr 15 (start at 13 UTC) 18/21cm, 6cm, 5cm or 1.3cm
     2015 May 12 - May 13 (start at 13 UTC) 18/21cm, 6cm, 5cm or 1.3cm
     2015 Jun 23 - Jun 24 (start at 13 UTC) 18/21cm, 6cm, 5cm or 1.3cm

     Please consult the e-VLBI web page at
     http://www.evlbi.org/evlbi/e-vlbi_status.html to check for possible
     updates, and for the available array.

     Successful proposals with an e-VLBI component submitted by the
     October 1st deadline will be considered for scheduling in the above
     e-VLBI sessions starting from Mar 24th 2015.

     Note that only one wavelength will be run in each e-VLBI session,
     depending on proposal priorities.

     See http://www.e-merlin.ac.uk/vlbi/evn_docs/guidelines.html for
     details concerning the e-VLBI observation classes and observing modes


     Features for the Next Regular EVN and e-VLBI Sessions
     -----------------------------------------------------
   * Both Jb1 and Jb2 will be available for EVN recording, as will
     simultaneous EVN+e-MERLIN operations with home-station EVN
     recording. For such simultaneous EVN+e-MERLIN operations, VLBI
     data from Cm will be made available at up to 512 Mbps (e.g. 64 MHz
     in both hands of circular polarization) on a best efforts basis.
     For updated information please consult the web at:
                     http://www.e-merlin.ac.uk/vlbi/

   * Please consult http://www.evlbi.org/evlbi/e-vlbi_status.html and
     the EVN User Guide http://www.evlbi.org/user_guide/user_guide.html
     for updates on the current EVN and e-VLBI array, availability of
     different stations per observing band and for the dates of the e-VLBI
     observing sessions.


     Global VLBI Proposals
     ---------------------
   * Global proposals can be proposed up to 1 Gb/s including VLBA,GBT,JVLA

   * Some modes may require different bandwidth channels from EVN &
     NRAO telescopes; correlation at JIVE can handle this

   * JIVE support staff and Amy Mioduszewski at Socorro will assist during
     the scheduling process of such observations

   * Global observations will be correlated at the SFXC correlator at JIVE
     (default) or at the DiFX correlator in Bonn (if
     appropriate justification is given in the proposal).


     RadioAstron Observations
     ------------------------
   * Proposals requesting the EVN as ground array support for RadioAstron
     proposals for the AO3 period (1 July 2015 - 30 June 2016) should be
     submitted at this deadline.


     Large EVN Projects
     ------------------
   * Most proposals request 12-48hrs observing time. The EVN Program
     Committee (PC) also encourages larger projects (>48 hrs); these
     will be subject to more detailed scrutiny, and the EVN PC may, in
     some cases, attach conditions on the release of the data.


     Availability of EVN Antennas
     ----------------------------
   * Medicina and Urumqi should return to the EVN from Session 1, 2015
     onwards. The Sardinia 64m telescope (SRT) remains in a commissioning
     phase but is available on a "best efforts" basis from Session 1, 2015.
     Robledo 70m telescope is occasionally available for EVN observations.
     From Session 1, 2015, the availability of WSRT as a phased array is not
     certain and WSRT may be participating with a single telescope.

   * Tm65 is the new 65 m telescope at Tianma, about 6 km away from
     the current 25 m Shanghai telescope. Both of these telescopes can observe at
     21, 18, 13, 6, 5, 3.6, and 3.6/13 cm. For now, Sh remains the default
     choice. Tm65 can be selected instead of (or in addition to) Sh, with the
     motivation for this choice discussed in the scientific justification.
     If you select both, you should also discuss the motivation for the very short baseline.
     See the EVN Status Table for details:
     http://www.evlbi.org/user_guide/EVNstatus.txt


     Use of Korean VLBI Network Antennas
     -----------------------------------
   * The Korean VLBI Network (KVN) has now become an Associate
     Member of the EVN (as from January 2014). KVN telescopes may be
     requested for EVN observations at 1.3cm and 7mm wavelengths. For
     more details regarding the KVN, see:
     http://kvn-web.kasi.re.kr/en/en_normal_info.php


     Use of Australian VLBI Network Antennas
     ---------------------------------------
   * It is planned that starting in Session 1 2015, some Australian
     Long Baseline Array (LBA) time will be made available for
     simultaneous scheduling with the EVN, thus enabling the
     possibility of joint LBA/EVN observations in that and future disc
     sessions. The easternmost stations of the EVN are in a similar
     longitude range to the LBA telescopes, and for sources in
     equatorial regions, baselines to western European stations are
     also achievable. Joint LBA time is likely to be heavily
     oversubscribed, and authors are requested to note whether they
     are prepared to accept scheduling without LBA antennas being
     present.

     Any proposals for joint EVN+LBA observations
     submitted to the LBA by its 15 December 2014 deadline
     should also be submitted to the EVN by the 1 February 2015
     deadline and will first be eligible for scheduling in EVN
     Session 2/2015.

     For more details regarding proposing time on the LBA, see:
     http://www.atnf.csiro.au/observers/apply/avail.html
     &
     http://www.atnf.csiro.au/vlbi/index.html

     EVN+LBA observations should be possible at all principal EVN wavebands from
     21 cm to 1.3 cm.: See: (http://www.evlbi.org/user_guide/freq_cov.html).


     Out of Session Observing
     ------------------------
   * Out-of-Session observing time (up to a maximum of 144 hours/year),
     is now available to all proposals. Proposals requesting Out-of-
     Session observing time must provide full scientific (and technical
     if appropriate) justification as to why observations must be made
     outside regular sessions. Out-of-Session observing blocks should
     be no less than 12 hours in duration (although individual
     observations can be shorter), and occur no more than 10 times per
     year (up to a maximum of 144 hours). Proposals should specify
     which dates/GST ranges are being requested and indicate the
     minimum requirement in terms of numbers of telescopes (and any
     particular telescopes). Proposals will only be considered for
     dates occurring after the regular EVN session that follows the
     proposal deadline. Observations requiring much shorter lead times
     should be submitted as "Target-of-Opportunity" proposals.


     How to Submit
     -------------
     All EVN and Global proposals (except ToO proposals) must be submitted
     using the NorthStar on-line proposal submission tool.
     Global proposals will be forwarded to NRAO automatically and should
     not be submitted to NRAO separately.

     When specifying your "Recording format" for Global modes in the
     EVN proposal tool, select 32. 64. 128, 256, 512, or 1024 Mbps from
     the "Specify aggregate bitrate (use network defaults)" menu

     New proposers should register at http://proposal.jive.nl.

     The SCIENTIFIC JUSTIFICATION MUST BE LIMITED TO 2 PAGES in length.
     Up to 2 additional pages with diagrams may be included.

     When specifying requested antennas from the LBA, please specify 'LBA'
     under the "other" row in the telescope-selection box - this selects
     all that are available for joint observations.

     The deadline for submission is 23:59:59 UTC on 1st February 2015.


     Additional information
     ----------------------
     Further information on Global VLBI, EVN+MERLIN and e-VLBI
     observations, and guidelines for proposal submission are available at:
