NAME
visible - calculates whether the telescope can point to an object
SYNOPSIS
visible [ut=hh:mm:ss] [date=dd/mm/yyyy] [window] [verbose]
DESCRIPTION
visible prints out the the hour angle, declination, the altitude and
azimuth of the object in decimal degrees. The input lines must arrive in
stdin and consist of lines containing the RA, Dec, and equinox of the
coordinates in hh:mm:ss dd:mm:ss yyyy format. If the position exceeds either
the hour angle, declination, or altitude limits of the telescope, additional
fields will be added, giving the cause of the violation(s). The status code
for either case is 0; only input errors cause non-zero status
codes.
The current local sidereal time is used unless over-ridden by the command
line value. The telescope limits as well as the latitude and longitude are
found in the file $HOME_DIR/
ait.config
where HOME_DIR is a required
environment
variable.
