2 Gaia DR3 phase plot Rektořík, Tomáš 2023-07-26 20:57 UTC Phase plot of the star from Gaia DR3 G band epoch photometry.
1 Phase plot Rektořík, Tomáš 2023-07-25 22:51 UTC Phase plot of CzeV4340 Lac created from TESS sectors 16, 17, 55, 56 light curve. The light curve was detrended with low-order polynomials and the amplitude was calibrated by normalizing absolute flux variation with the theoretical flux value of the star given its TESS magnitude.
