This is a routine for retrieving a catalogue file of dynasonde data.
Inputs have to be in an exact order, but the line of input arguments can be truncated at any point.
These numbers can be truncated at any point too. In this way, a catalogue of data covering a whole week or month is possible. It is important to remember however, that when the analysis program, dyAn , acts on files from a catalogue, it writes the results to a single file. For this reason, it is recommended that the user analyses data from a single day at most. This option exists in order to expand the database to other sounders if required.
