This routine transforms axis values by taking the logarithm (base 10). The inverse exponentiates the supplied axis values. It is intended for use as a transformation routine by an AST IntraMap.

CALL KPG1_ASLOG( THIS, NPOINT, NCOORD_IN, INDIM, IN, FORWARD, NCOORD_OUT, OUTDIM, OUT, STATUS )

STATUS = INTEGER (Given and Returned)

• Bad input co-ordinates will be set to AST__BAD, but TRANSFORM uses VAL__BADD to mark bad values. We assume here that VAL__BADD and AST__BAD are the same.
