Detailed Filename Syntax

This section describes the full syntax for the CFITSIO FITS file names, which can contain the following components:

filetype://BaseFilename(outName)[HDUlocation][colFilter][rowFilter][binSpec]

where each of these components is described below. The filetype, BaseFilename, outName, and HDUlocation components, if present, must be given in that order, but the colFilter, rowFilter, and binSpec specifiers may follow in any order. Regardless of the order, however, the colFilter specifier, if present, will be processed first by CFITSIO, followed by the rowFilter specifier, and finally by the binSpec specifier.
