Bad pixels are replaced with 65535 as the previous default FITS NaN caused problems for some other tools.

The FITS-WCS encoding is set to "FITS-WCS(CD)" to describe the rotation and scaling as a CD matrix rather than as PC matrix with CDELT values.

The ORIGIN is set to ’LCOGT’ .

Only the Data component is converted, along with the FITS extension of the NDF and any NDF history records - any other NDF extensions (such as CCDPACK’s) are not converted.
