When specifying the name of the output FITS file to be created at run time, the user can indicate that images should be written in tile-compressed format by enclosing the compression parameters in square brackets following the root disk file name. Here are some examples of the extended file name syntax for specifying tile-compressed output images:
myfile.fit[compress] - use the default compression algorithm (Rice)
and the default tile size (row by row)
myfile.fit[compress GZIP] - use the specified compression algorithm;
myfile.fit[compress Rice] (only the first letter of the algorithm
myfile.fit[compress PLIO] name is required)
myfile.fit[compress HCOMPRESS]
myfile.fit[compress R 100,100] - use 100 x 100 pixel tile size
myfile.fit[compress R 100,100;2] - as above, and use noisebits = 2
