Abstract:
We study LQ Hya photometry for 1982-2014 with the carrier fit (CF)
method. As a result global continuous model for the light curve is
built.
Description:
The epochs as well as differential magnitudes of primary and secondary
minima obtained from the model are presented. The analysis was done
for the homogeneous data set D2 as denoted in the paper (photometry
obtained with the T3 0.4m APT at the Fairborn Observatory).

Note (1): The reliability criteria are defined in sect. 3.4 in the paper i
The reliability code is:
1 = minimum is reliable
0 = minimum unreliable
The reliability criteria are defined in sect. 3.4 in the paper.
