Most eclipse commands are written to deal with images or cubes in FITS format, but the need to support FITS tables has arisen with some of the latest instrument recipes. Some ISAAC recipes expect FITS table in input, or produce FITS-compliant tables in output. This means that most users dealing with these tables need a way of dumping them to see what they contain, with no more than a command-line.
dtfits offers this service: it accepts a single name on its command-line, and will dump header information and contents of the given FITS table (be it ASCII or binary).
