carr_cea_wcs_header

pfsspy.utils.carr_cea_wcs_header(dtime, shape, *, map_center_longitude=<Quantity 0. deg>)

Create a Carrington WCS header for a Cylindrical Equal Area (CEA) projection. See [1] for information on how this is constructed.

Parameters:

  • dtime (datetime, None) – Datetime to associate with the map.

  • shape (tuple) – Map shape. The first entry should be number of points in longitude, the second in latitude.

  • map_center_longitude (astropy.units.Quantity) – Change the world coordinate longitude of the central image pixel to allow for different roll angles of the Carrington map. Default to 0 deg. Must be supplied with units of astropy.units.deg
