This routine correctly processes the AXIS, DATA, QUALITY, LABEL, TITLE, UNITS, HISTORY, WCS, and VARIANCE components of an NDF data structure and propagates all extensions.
Processing of bad pixels and automatic quality masking are supported.
All non-complex numeric data types can be handled. Arithmetic is performed using single-precision floating point, or double precision, if appropriate, but the numeric type of the input pixels is preserved in the output NDF.
