plotParallacticAngle
Return to directory of Todd's CASA extensions
Plot the parallactic angle for a given RA/Dec, and over a specified range of LST or hour angle. See also
parallacticAngle.
Usage:
au.plotParallacticAngle(radec, mjd=None, date=None, observatory='ALMA', incrementMinutes=3.0,
xaxis='lst', haRange=None, lstRange=None)
Inputs:
- radec: a sexagesimal string or a float list: [raRad, decRad]
- mjd: MJD to use
- date: date/time string to use
- xaxis: 'mjd', 'lst', or 'ut'
- haRange: if specified, then limit the hour angle to specified range
- lstRange: if specified, then limit the hour angle to specified range
- If no date is specified, it uses the current date/time.
Returns:
- the range of parallactic angle as a list
Example:
CASA <7>: au.plotParallacticAngle('17:51:00 09:39:00', date='2015-06-21', haRange=[-3,3])
MJD= 57194.00000, MJDseconds= 4941561600.0, JD= 2457194.50000
LST range = 6.0 hours, parallactic angle range = 105.513389 deg
