ASTDISP

ASTDISP

Name


ASTDISP

Purpose


Print astronomical and pixel coordinates in a standard format

Explanation


This procedure (ASTrometry DISPlay) prints the astronomical and
pixel coordinates in a standard format. X,Y must be supplied. RA,DEC
may also be supplied, and a data number (DN) may also be
supplied. With use of the Coords= keyword, a string containing the
formatted data can be returned in addition or instead (with /silent)
of printing.

Calling Sequence


ASTDISP, x, y, [Ra, Dec, DN, COORD = , /SILENT ]

Input


X - The X pixel coordinate(s), scalar or vector
Y - The Y pixel coordinate(s), scalar or vector

Optional Inputs


RA - Right Ascension in *degrees*, scalar or vector
DEC - DEClination in *degrees*, scalar or vector (if RA is supplied, DEC must also be supplied)
DN - Data Number or Flux values
Each of the inputs X,Y, RA, DEC, DN should have the same number of
elements

Optional Input Keywords


SILENT Prevents printing. Only useful when used with Coords=

Output


Printed positions in both degrees and sexagesimal format
All passed variables remain unchanged

Optional Keyword Output


COORDS Returns the formatted coordinates in a string

Procedures Called


ADSTRING - used to format the RA and Dec
