This is an old revision of the document!
This is done on hex2. Below, post-processing of AUST10 is shown as an aexample
Binary files (qcodes
and snratio
) are in ~/bin
Make sure the directory 1234 for AUST10 is in /data/AUSTRAL/aust10
$ cd /data/AUSTRAL/aust10/12434 $ alist -f alist.ed.out > edit dup SNR > psfile 1234.psfile_rf give full path to 1234.ovex file $ codes
when prompted, enter “aust10 1234”
This will create the file 1234.qcodes
. Note qcodes expects to find the psfile in /data/AUSTRAL/aust10/1234/1234.psfile_rf
so check path is correct and change name of aust?? directory to lower case if needed'
You need the a priori SNR values which sked can generate. Currently sked is only running on a virtual machine on Jim's Mac! A-priori SNRs for AUST10 to AUST16 have been done. To do this, on the virtual machine:$ cd ~/schedules $ ./snrlist.sh aust11.skd $ ./snrlist.sh aust12.skd $ ./snrlist.sh aust13.skd $ ./snrlist.sh aust14.skd $ ./snrlist.sh aust15.skd $ ./snrlist.sh aust16.skd
All output files copied tohex2:/data/AUSTRAL/snr_apriori
Back on hex2:
$ cd /data/AUSTRAL/aust10 $ mkdir SNR $ cd SNR
Copy the final alist file, stations.m
and aust10_snr.apriori
to the SNR directory.
You can get stations.m
from a previous experiment. Make sure the single letter codes match the two letter codes as defined earlier in the processing. Check by looking in a scan sub-directory (e.g. ../1234/185-0700/<source>.wzpetk
) and edit the stations.m
file if necessary.
In the case of aust10:
Ke=i Hb=L Ht=g Yg=x
To avoid memory stack problems in snratio:
$ ulimit -s 102400 $ ~/bin/snratio aust10_snr.apriori alist.ed.out
This produced an error message:
“Could not match S baseline Lg from alist”
Lg = Hb-Ht, but the apriori file has this baseline as Ht-Hb (i.e. gL), so edit line 2 of the apriori file and change Ht-Hb to Hb-Ht. OK now
Check /data/AUSTRAL/Stations_Codes_CR.txt
agrees with coding used for experiment
Create a file called /data/AUSTRAL/aust10/1234/aust10.txt
with some header information (see previous experiments for examples)
Put vex and v2d files from Curtin (name them aust10.vex
, aust10.v2d
) into /data/AUSTRAL/aust10
$ WriteCR.pl
For the correlation dates use the Curting data release date as the end and one day previous as the start.
Output file is called /data/AUSTRAL/aust10/1234/aust10.corr.perl
Edit the file and add any correlator or station notes by hand. Note the database entry is currently blank.
