  • vis: measurement set
  • field: field ID or string name
  • verbose: if True, then print the derived time range
Returns: a dictionary of parallactic angles (in degrees), keyed by 'min', 'max', and 'mean'

Example:

CASA <3>: au.parallacticAngleForField('uid___A002_X5f231a_Xfb0.ms',0)
MJD: 56378.328515-56378.334303 = 07:53:04-08:01:24 UT
