Synopsis

Write a FITS file from a Casacore Array. Returns False if there is any proglem. The data is written into the primary data array, and the data is written in floating point (BITPIX=-32). If the operation fails, ErrorMessage will contain an informative error. At the moment this probably isn't bulletproof enough at finding errors on output.

If any of unitName, axisNames, refPixel, refLocation, or delta are non-null, the corresponding FITS keywords (BUNIT, CTYPEn, CRPIXn, CRVALn, CDELTn) are set. CRVALn is corrected for the difference in addressing between FITS and Casacore (1 vs. 0). If a Vector pointer is non-null, then that vector must be the correct length.

If keywords is non-null, the contents are written out as FITS keywords. The names are upper-cased and truncated to 8 characters (yuck). No other validation is done (e.g. that SIMPLE or NAXIS is not in the map).

If objectName is non-null, the OBJECT keyword is set.

BITPIX can presently be set to -32 or 16 only. When BITPIX is 16 it will write BSCALE and BZERO into the FITS file. If minPix is greater than maxPix the minimum and maximum pixel values will be determined from the array, otherwise the supplied values will be used and pixels outside that range will be truncated to the minimum and maximum pixel values (note that this truncation does not occur for BITPIX=-32).
