Return to directory of Todd's CASA extensions

Runs J2000ToICRS on a grid of directions in the celestial sphere and provides statistics.


au.J2000ToICRSgrid(ra_inc=0.5, dec_inc=5, separation=5.0)
  • ra_inc: increment of RA grid in hours
  • dec_inc: increment of Dec grid in degrees
  • separation: angle to calibrator (at random p.a.) for computing the net difference in the effect
