altaz command

altaz - calculates the altitude and azimuth of a celestial object

altaz [iso=yyyy-mm-ddTHH:MM:SSZ] [high] [decimal] [nodut]

This program accepts lines containing coordinate strings similar to from the standard input:

echo ra=13:12:12 dec=23:0:23 equinox=2000| altaz

It then concatentates, the altitude, azimuth, and parallactic angle in decimal degrees. The hour angle and declination in degrees are a courtesy.

ra=13:12:12.01 dec=+23:00:22.77 equinox=2017.567 epoch=2017.567 mode=topocentric alt=50.9765 az=3.1032 pa=-176.759 ha=-2.1222 airmass=1.287

The other fields following the first four on the input are copied verbatim.

You can use the program to go the other way (alt,az --> ra,dec) if you wish.O

The current time is used unless overridden by the command line options. The latitude and longitude are derived from the the telescope server rtel.

iso= use iso date instead of present time.

high - prints out the coordinates with too many significant figures.

decimal - prints out the RA and Dec in decimal degrees.
