DESCRIPTION

POPS is a Miriad task which converts equatorial positions from one epoch to another. Accuracy is about 1 arcsec. If an observatory is also given, POPS gives other source information, such as radial velocity, source rise and set time and source elevation and azimuth.  

PARAMETERS

radec
Right ascension and declination, given as hh:mm:ss,dd:mm:ss. These coordinates are assumed to be mean coordinates of the given epoch. The mean, true and apparent coordinates are printed on output.
epochs
The input and output epochs. The epochs can be given as either Bxxxx or Jxxxx (where xxxx is a year, e.g. B1950 or J2000), or as yymmmdd:hh:mm:ss, a time in normal Miriad format (e.g. 93JAN05:10:25:00).
telescop
Observatory name. Default is the geocenter.
