Hi Stuart,

Detailed correlator records from Curtin are linked from
http://cira.ivec.org/dokuwiki/doku.php/correlator/records
(also linked from the front page of the LBA observers wiki under
"Miscellaneous --> Curtin Correlator Records")

Since 2011 a summary of correlated data is kept in a spreadsheet
linked from the top of the page (including "hours observed" and "hours
OK" for each station per experiment - this is total elapsed time not
on-source time. The link is for the web page view - you may need to
click on the page then scroll far to the right to see the "hours OK"
where Warkworth participated.) The spreadsheet view is here:
https://docs.google.com/spreadsheets/d/1IQHptTqiYVieeZE2qoKxAgjmOrM6_QfMYn9D-nvHua4/edit?usp=sharing

Please note that I'm sometimes behind on filling in the hours
scheduled/hours OK columns, but "Correlation finished" column etc. are
usually filled in straight away.

Also, the experiment code column in the spreadsheet links to a page
for each experiment
 http://cira.ivec.org/dokuwiki/doku.php/correlator/records/{expcode}

which has various plots from our data pipeline (which can be grabbed
from ftp area ftp://cira.ivec.org/{expcode} e.g. with 'wget', if you
prefer).

For astronomical experiments the "recorded scans" vs "used scans" is
not necessarily as straight-forward as for geodesy, since in general
the observations may use phase-referencing to detect weak targets; our
pipeline diagnostic plots do not go this far at the moment. But the
fringe delay plots usually indicate if fringes are detected on
calibrator/fringe-finder scans. We probably could provide some
additional text output statistics as well as the graphics if this
would be more useful. (Also, in some cases if fringes are not detected
on weaker calibration source scans in the pipeline it doesn't
necessarily mean the data are useless - e.g. more freq averaging can
be performed after some initial steps to improve S/N on phase-ref
calibrators.
I count "hours OK" if the data otherwise look OK and there were no
other problems evident or reported.)

(Also note that the CIRA wiki and ftp area will be moving to a
different server some time soon as iVEC will no longer provide this
service for us from the end of July. We're hoping the same domain name
will still work though so this should be transparent. Cormac should be
able to provide more details on that if/when it becomes an issue. In
principle I suppose we could also copy everything to ATNF..)

Similarly there's a Curtin AuScope correlator records spreadsheet
https://docs.google.com/spreadsheet/ccc?key=0Al7YbLo5pvvidEtwWkJBUF9OVHFvc1JLOFMxd1J2UHc&usp=drive_web#gid=0
That is populated as data are correlated, before the geodetic analysis.

Cheers,
Hayley
