Next: Required observational data Up: File Formats Required Previous: CCD photometry . Every instrument seems to produce its data in a different format. However, it is relatively simple to re-format the data to a standard form; MIDAS table files are the obvious standard form to use. Usually the conversion is done in two steps: first reformat the existing data as an ASCII file with all records in the same format, and then convert this ASCII file to MIDAS table format. ...
