PVMax(i)
-
Maximum number of FITS-WCS projection parameters
- Description:
- This attribute specifies the largest legal index for a PV projection
parameter attached to a specified axis of the WcsMap (i.e. the
largest legal value for "m" when accessing the "PVi_m" attribute).
The axis index is specified by i, and should be in the range 1 to 99.
The value for each axis is determined by the projection type specified
when the WcsMap
is first created using astWcsMap and cannot subsequently be
changed.
- Type:
- Integer, read-only.
- Class Applicability:
-
WcsMap
-
All WcsMaps have this attribute.
