.TH skycoor 1 WCSTools "9 November 2001"
.SH Name
skycoor \- Convert coordinates
.SH Synopsis
skycoor [\-bdgjv] [\-n ndec] ra1 dec1 sys1 ... ran decn sysn
.br
or

skycoor [\-vbjg] [\-n ndec] @listfile
.SH Description
.I 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
.SH Options
.TP
.B \-b
B1950 (FK4) output
.TP
.B \-d
RA and Dec output in degrees
.TP
.B \-e
Ecliptic longitude and latitude output
.TP
.B \-g
Galactic longitude and latitude output
.TP
.B \-i r|d|
Input units (r=radians, d=degrees, else hh:mm:sss dd:mm:sss)
.TP
.B \-j
J2000 (FK5) output
.TP
.B \-n <num>
Number of decimal places in output RA seconds
.TP
.B \-o <num>

.B \-p
RA and Dec proper motion in milliarcseconds/year
.TP
.B \-q
Output system, including equinox
.TP
.B \-r <RA> <Dec> <RA> <Dec>
