# Varfind curve format

The Varfind (mag-dev) curve file consists of table of indexes, mean magnitudes and standard deviations for all detected stars. Such data is intended for detecting variable stars on a set of CCD frames. Magnitudes are always in differential form, they are relative to the comparison star.

Output files are stored in the ASCII format; the end of the line is represented by `CR+LF` in the DOS/MS Windows environment and by `LF` in the Unix/Linux environment. First line contains a list of column names separated by single space character. Second line consists of additional information and has no special formatting, it must not start by number, though.

On the following lines, the table values are stored. The values are separated by tab character or single space, rows are separated by the end-of-line character (see above). Parsers must ignore all additional white characters. See table 1 for short description of columns.

Keyword | Description
--- | ---
INDEX | Ordinal number of a star in the reference file
MEAN_MAG | Mean relative magnitude of a star
STDEV | Standard deviation of previous value
GOODPOINTS | Number of measurements used for computation
