fig4.dat:
---------
This file contains the standard UBV magnitudes and colors of the 74 stars with reliable (U-B) color indices.
columns:
1-3: RA [hour, min, sec]
4-6: DEC [deg, min, sec]
7-8: V magnitude and uncertainty [mag]
9-10: (B-V) colour index and uncertainty [mag]
11-12: (U-B) colour index and uncertainty [mag]



fig7.dat:
---------
This file contains the standard V magnitudes and (B-V) colors and instrumental (u-b) colors of all observed stars.
columns:
1-10: same as in fig4.dat
11-12: instrumental (u-b) color index and uncertainty [mag]
13: number of CCD where the star was observed



ls_params.dat:
--------------
Parameters of the least squares fits for the discovered periodic variable stars. fi, Ai and Ti respectively denote the
frequencies, semi-amplitudes and times of maximum light of the detected terms. The initial epoch T0 is HJD 2453000.0.
sigma_res and DT respectively denote the standard deviation of the residuals and the detection threshold. [A] in last
column indicates that the frequencies were calculated the from ASAS-3 photometry and have been fixed during the least
squares fitting to the WFI data.



light_curves:
-------------
The three subdirectories contain the light curves in U, B and V bands. File names follow the ID column from Table 2.
If a star was observed on more than one CCD, its time series is split into files named vNNN-C.dat, where NNN is the ID
from Table 2, and C is the CCD number.
columns:
1: time [HJD-2453000.0]
2-3: differential magnitude and uncertainty [mag]
4: airmass
