trackingtime

NAME

trackingtime- compute LST rise, transit, and set times for sources as well as time in the keyhole

SYNTAX

trackingtime {--help --lim --sort --usecalib --usepsr --usex102 --usefluxgt1 --zamax=zamax --zamin=zamin --exclnorise} srcfile

ARG

srcfile name of cima source file to process. The file format is:

srcname hhmmss.s ddmmss.s j/b The routine will also read hh:mm:ss.s dd:mm:ss.s
# in column 1 of the file is a comment line and will be ignored.

Options

--help output help message and exit

---lim set zamin 3.5, zamax=12 . These are the limits during the platform beam repair.

---sort sort the output by ascending ra.

--usecalib use cima calibrator file calib.cat (ignore srcfile)

--usepsr use cima pulsar file psr.cat (ignore srcfile)

--usex102 use the x102 calibrator file calib.cat (ignore srcfile)

--usefluxgt1 use the point file with calibrators gt 1 jy at lband

--zamax=zamax set zamax to zamax degrees (def 19.69)

--zamin=zamin set zamin to zamin degrees (def=1.06)

--exclnorise exclude sources that never rise.

DESCRIPTION

    trackingtime is a shell script that calls idl routines to process the srcfile and output the lst rise, transit, and set times for each source in the file. It also outputs the Solar time from rise to keyhole and keyhole to transit. The user can change the za limits with --zamin,--zamax options as well as with --lim. The output goes to standard out. The --sort option will sort the output by ra (the default order is how it is in the srcfile).

    The routine will normally process the srcfiles that users create and pass to cima. The options --usecalib, --usepsr, --usex102 will ignore srcfile and use one of the standard cima catalog files.

    The never rises column that follows the source name will have a 1 in it if the source za is alway greater than zamax.

EXAMPLES

Look at the a2463 srcfile tracking times for the 3.5 to 12 degree za limits:

trackingtime --sort /share/obs4/usr/a2463/a2463.list

zaMax:      12.0000 zaMin:      3.50000

Notes:

Rise to keyhole is the solar minutes from rise to hitting the keyhole (in the center).
Keyhole to transit is how long it takes from hitting the keyhole till transit. The time in the keyhole is twice this value.
if keyhole to transit is 0 then the source never enters the keyhole and risetokeyhole equals rise to transit.
