skycoor converts coordinates between the J2000, B1950, and galactic coordinate systems, rounding to a specified number of decimal places and printing in degrees or hh:mm:ss.sss dd:mm:ss.sss.  Input coordinates may also be in either format, and the system (J2000, B1950, or galactic) may be in upper or lower case.  No spaces are allowed within  the individual coordinates

-b

B1950 (FK4) output

-d

RA and Dec output in degrees

-e

Ecliptic longitude and latitude output

-g

Galactic longitude and latitude output

-i r|d|

Input units (r=radians, d=degrees, else hh:mm:sss dd:mm:sss)

-j

J2000 (FK5) output

-n <num>

Number of decimal places in output RA seconds

-o <num>

Offset coordinates by this many arcseconds

-p

RA and Dec proper motion in milliarcseconds/year

-q

Output system, including equinox

-r <RA> <Dec> <RA> <Dec>

Angular separation between two RA, Dec pairs

-s

Output ra= dec= epoch= radecsys= for sethead

-v

Print more intermediate information

-w

Convert RA, Dec equatorial coordinates to x,y,z

-x

Convert x,y,z equatorial coordinates to RA, Dec

-y <epoch>

Epoch of coordinates in years
