BDFLIST: Verb runs OBIT task ASDMList to list ASDM file contents
DOWAIT -1.0 3.0 > wait for and display output
DOCRT -4.0 132.0 > 0 display output on
terminal, else message file
OBITVERS 0.0 =3 for python3, else 2
ASDMFILE Full path name to ASDM dir.
Use: The OBIT package of astronomy software written by Bill Cotton
of NRAO Charlottesville is available at some institutions. If
it is available and in your $PATH, then you may use this verb
to list the contents of an EVLA ASDM data file.
The log and run file for each execution of BDFLIST will appear
in your $HOME area.
The input adverbs are saved with a TPUT equivalent when this
verb is invoked.
DOWAIT.....A log file is written into your $HOME area from the obit
task. If DOWAIT <= 0.0, AIPS does not wait for the OBIT
task BDFList and you will need to look at the log file
with more, less, cat, or an editor. If DOWAIT > 0, AIPS
will wait for BDFList to finish and then echo the log
file under control of DOCRT. Note that this is different
from DOWAIT in other OBIT access verbs since BDFList is
DOCRT......> 0 Use the terminal, the full length of the log file
lines will appear so widen it at least a little.
<= 0 Write log file to message file at level 0 (no echo
to the terminal). Some messages may get truncated.
OBITVERS...OBIT now is designed to run on python 3 or 2.7. If you
have a newer version of OBIT (post 01-Apr-2021) then you
may want the python3 version. Set OBITVERS to 3.
Otherwise python2 will be invoked.
ASDMFILE...The full path name to and including the top directory of
the ASDM/BDF data. Two 64-character strings may be used
for long names. The ASDMFILE(2) will be appended to the
non-blank portion of ASDMFILE(1) to generate the name
used. The code will also manage when ASDMFILE(1) begins
with either '$xxxx/' or 'xxxx:' where xxxx is a logical
(environment) variable. The filename sent to OBIT will
be the translation of $xxxx followed by a '/' followed by
an remaining non-blank characters in ASDMFILE(1) followed
NOTE: There is also a stand-alone script named BDFLIST. Its help file
information appears below:
Type: Stand-alone service program
Use: BDFLIST is a script that will read an EVLA ASDM/BDF format data
area and list its contents in a log file and on your terminal.
It does this by invoking a task in the obit software package
written by Bill Cotton. That package must be available on your
system and the script ObitTalk must be in your path. If you do
not have obit, it may be obtained from www.nrao.edu and should
install fairly easily.
BDFLIST is a script that is run at the command line (i.e.,
outside of AIPS). It will ask you a few essential questions.
1. "BDF dir-path :"
Give the full path name to the directory containing the
ASDM and BDF data. These data may be obtained from the
2. "AIPS usrnumb :"
Give the AIPS user number you wish to use for these data.
This is required for some reason.
BDFLIST will list the contents of your ASDM area. This will
allow you to see what is there and to determine the
"configuration number" which you need to give to BDF2AIPS in
order to translate your ASDM/BDF format EVLA data into AIPS.
Each configuration is fully described and then all scans in the
data set are listed giving scan number, source name, time
range, configuration number, and intent.
BDFLIST will write a log file and a run file in your /tmp area
with the time included in the name. This file is echoed to the
screen as BDFLIST finishes and will remain in /tmp until it is
automatically deleted by the operating system.
