This routine creates an AST PolyMap that implements the polynomial transformation described by a supplied Starlink POLYNOMIAL structure (see SGP/38).

CALL KPG1_CH2PM( LOC, POLYMAP, STATUS )

LOC = CHARACTER $\ast$ ( DAT__SZLOC ) (Given)

POLYMAP = INTEGER (Returned)

STATUS = INTEGER (Given and Returned)

• The returned PolyMap has a defined forward transformation (equivalent to the supplied POLYNOMIAL), but no inverse transformation.

• Both CHEBYSHEV and SIMPLE variants of the POLYNOMIAL structure are supported. But currently only 1- or 2- dimensional Chebyshev polynomials can be handled. An error is reported for Chebyshev polynomials of higher dimensionality.
