The celcoo program ("celestial coordinates") converts right ascension and declination to hour angle, altitude, and azimuth, for a given place and time.
The program was assembled from pieces of other programs, mainly starmap and additions I had made to planet.
The celcoo program has these options:
Usage: celcoo -R HhMmSs -D DoM'S" [-t H:M:S] [-d m/d/y] [-z tz] \
[-a DoM'S"] [-o DoM'S"]
where
R = right ascension (H=hours, M=minutes, S=seconds)
D = declination (D=degrees, M=arcminutes, S=arcseconds)
t = time (H=hours, M=mins, S=seconds; 24-hour clock, default=now)
d = date (month/day/year, must supply all digits of year, default=today)
z = timezone number (count west from Greenwich, default=central)
a = latitude (DoM'S" [D=degrees, M=mins, S=secs] north, default=42o2')
o = longitude (DoM'S" [D=degrees, M=mins, S=secs] west, default=88o16')
In all parameters, the (arc)seconds may be omitted, or (arc)minutes and
(arc)seconds may be omitted. Also, the symbol after the last number (hmso'":)
may be omitted. Use negative latitude for south, negative longitude for east.
You have to provide the right ascension and declination, but the rest are
optional. Don't type any [brackets] or backslash.
Type everything on one line. Note that
the option letters for RA and declination are capital R and D, not small
letters.
Example:
celcoo -R 13h27 -D 44o22 -d 9/26/2014 -t 21:30
and it tells you
