I am working on VLA HI-line data obtained 2006 Dec 14 and Dec 16. At
that time there were 6 EVLA antennas in the configuration. I am
getting lots of large phase closure errors with those antenna.
Michael Rupen had advised Elias Brinks, who had a similar problem
with data taken on Dec 15, that the problem was poor antenna
positions and this could be corrected with VLANT. I have tried to use
VLANT on my data but it bombs with the following message:
tortug> VLANT1: Task VLANT (release of 31DEC07) begins
tortug> VLANT1: TFETCH: wget OF DATA FILE FAILED
tortug> VLANT1: ERROR 2 OPENING FILE FOR YEAR 2007
tortug> VLANT1: Purports to die of UNNATURAL causes
My inputs to VLANT are
AIPS 1: VLANT Task to apply VLA antenna position corrections from OPs
AIPS 1: Adverbs Values Comments
AIPS 1: ----------------------------------------------------------------
AIPS 1: INNAME 'AH918DEC14_2' Input UV file name (name)
AIPS 1: INCLASS 'CH 0' Input UV file name (class)
AIPS 1: INSEQ 1 Input UV file name (seq. #)
AIPS 1: INDISK 1 Input UV file disk unit #
AIPS 1: SELBAND -1 Bandwidth to select (kHz)
AIPS 1: SELFREQ -1 Frequency to select (MHz)
AIPS 1: FREQID 1 Freq. ID to select
AIPS 1: SUBARRAY 0 Input subarray = AN file
AIPS 1: GAINVER 0 Input CL table 0=>high
I am running AIPS version 31DEC07 and run a MNJ on the 23rd of each
month. My computing system is a Mac Dual 2.7 GHz PowerPC G5 running
Mac OSX Version 10.4.9.
Thank you for your help.
