ProjP(m)ProjPm - FITS-WCS projection parameters

Description:
This attribute provides aliases for the PV attributes, which specifies the projection parameter values to be used by a WcsMapWcsMap when implementing a FITS-WCS sky projection. ProjP is retained for compatibility with previous versions of FITS-WCS and AST. New applications should use the PV attibute instead.

Attributes ProjP(0) to ProjP(9) correspond to attributes PV$<$axlat$>$_0 to PV$<$axlat$>$_9, where $<$axlat$>$ is replaced by the index of the latitude axis (given by attribute WcsAxis(2)). See PV for further details.

Type:
Floating point.
Class Applicability:
WcsMap
All WcsMaps have this attribute.
