Runs
J2000ToICRS on a grid of directions in the celestial sphere and provides statistics.
Usage:
au.J2000ToICRSgrid(ra_inc=0.5, dec_inc=5, separation=5.0)
Inputs:
- 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
Example:
CASA <2>: au.J2000ToICRSgrid(0.5,3)
Grid of 2880 directions: Max=23.191524, Min=0.059000, Median=19.153257, Mean=18.037198 mas
Deltas for 5.0 deg offset: Max=2.029796, Min=0.000032, Median=0.395965, Mean=0.503825 mas
