class pycrtools.grid.CoordinateGrid(obstime=None, ut1_utc=0.0, L=None, phi=None, **kwargs)

Coordinate grid for images.

Has the following attributes (where N is the number of pixels):

pixel array of length N with pixel coordinates

(e.g. 1, 1, 2, 2, ..., naxis1, naxis2)

world array of length N with corresponding world coordinates

(e.g. J2000, AzEl) in radians

j2000 array of length N with corresponding J2000 coordinates in radians

(equal to world if grid type is J2000)

azel array of length N * 3 with corresponding azimuth, elevation,

distance coordinates in radians

cartesian array of length N * 3 with corresponding local Cartesian

coordinates in meters

pycrtools.grid.casaRefcodes(**kwargs)

Get CASA reference code and projection from standard WCS parameter parsing rules.
