NAME
srcTimes - compute LST rise, transit, and set times for sources.
SYNTAX
srcTimes -b -r -t -s -w -x -z zaMax < inputFile > outputfile
ARGS
-b coordinates are in B1950. The default is J2000.
-r don't output rise times. (default is output rise times).
-t don't output transit times. (default is output transit
times).
-s don't output set times. (default is output set times).
-w Input format is : srcName hh mm ss.s dd mm ss.s
-x Input format is: srcName hhmmss.s ddmmss.s
-z zaMaxDeg. This is the maximum za attainable. default:19.69
(dome max za).
The default input file format is:
hhmmss.s ddmmss.s
DESCRIPTION
srcTimes will compute the rise, transit, and set LST
for a set of sources at arecibo.The default input format is:
hhmmss.s ddmmss.s (one source per line).
This can be changed with the -w or -x options. The default epoch is
J2000. The -b option will change the epoch to B1950. The output format
will have an optional sourcename (if the input format includeded it) followed
by :
RA DEC
RISE TRANSIT SET
hh:mm:ss dd:mm:ss hh:mm:ss hh:mm:ss hh:mm:ss
You can exclude the rise, transit, or set times with the -r,-t,-s optiopns.
The rise/set times are determined by the maximum zenith angle for the feed.
The default is 19.69 degrees (for the dome). If you are using the carriage
house then change the maximum za to 19.99.
EXAMPLES
-
Enter a line at a time from the terminal using the default format, epoch:
srcTimes
010725.0 322445.2 .... rise
transit set times
01:07:25.0 32:24:45.2 00:06:17
01:07:34 02:08:50
022610.3 342130.3
02:26:10.3 34:21:30.3 01:34:52
02:26:19 03:17:47
ctrl-d to exit
-
Compute all of the rise, set times for the B1950 sources in calib.cat.
The file format is:
srcName hhmmss.s ddmmss.s comments....
Don't bother to output the transit times.
grep "^B" /share/obs4/usr/aoui/calib.cat|srcTimes -b -x -t > calib.cat.times
Note that this has not processed the J2000 source names in the file.

ARCHITECTURES
srcTimes is compiled to run on sun Solaris machines. It needs
access to the observatory position which is in the file /home/online/vw/etc/Pnt/obsPosition.dat.
This file is accessible from most AO cpus (but not from the host "remote").
