Structure
of the datafiles
Generally, the structure of the *.xls datafiles is:
Column A - The name of the variable star
Column B - The J.D. of Min / Max
Column C - Note (if there are any)
Column D / E- The Reference/s and the page (if
available).
Column E – The type of the observation ( vis , pg ,
pe, CDD etc.) If the type of the observation is not available, this cell
is blank.
Column F - The name of the Author/s of the
observations, or the name of the Editor/s of the paper, or the name of who have
obtained the extrema from the photographic plates.
Sometime the Author/s of the observations of long
period variable stars wrote, in addition, the J.D. of the minimum of light of
the variable star. In some datafiles this is indicated in the column
"note" .
Column G - The year of publication of the paper.
