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 :ref:`1 <table:fnd_head>` 
for short description of columns.
