HEB (with Adam) 6 Oct 2009.
SVN checkout setup.bash (new version)
Edit ROOT PATHS in setup.bash:
Check/edit libraries, perl version etc.
source /nfs/apps/corr/DiFX-2.0beta/setup/setup.bash (add to .bashrc - but comment out line 'echo “ DiFX version $DIFX_VERSION is selected” ' for interactive login)
In each each area see README for commands to run
Binaries go to $DIFXROOT/bin/
See vex2difx documentation for .v2d file setup instructions.
ANTENNA blocks - 2 letter station codes
include ATCA X,Y,Z
EOP + clocks can be inserted in .v2d file (our method for v252k) or appended to vex file
Experiment on MJD 54885 - get EOPs for 5488[3..7] from usno_finals.erp
Polar motion: .erp uses 0.1 arcsec; .v2d requires arcsec
UT1-UTC: .erp uses microsec; .v2d requires offset seconds
* Adam fixed bug in vex2difx where S2 mode calculation was wrong (ch2tracks): #tracks=#channels (not #bits)
In .v2d can override default parameters e.g. for maximum output file size [2 GB], maximum length of job [7200s] by specifying maxSize and maxLength.
in SETUP block, new parameters for efficiency: xmacLength (=32 for 32 channels, needed for v252k) and strideLength (=8)
RULE block (we use setup = default)
- split in two halves (mjdStart and mjdStop), change Tid name and positions in each
- in resulting .input file, insert FREQ OFFSET for O'Higgins (-80000.0 Hz)
calcif2 <file_prefix>.calc - also needs <file_prefix>.input
Run in Socorro for v252k 1st half, use CR's machine as CALC_SERVER here for second half (start on unctious with /home/creynolds/data2/difx/bin/startCalcServer). Comparison done for 1st half: identical .im
We use mpirun as usual (make sure pointing to correct version of mpifxcorr)
(machines, threads file same as for earlier versions)
Makes directory <file_prefix>.difx - need to remove or rename before restarting.
