With an updated version of the W-D program, photometric solutions were simultaneously derived from BV light curves. Results indicate that AX Cas is a semi-detached binary with a mass ratio of q = ...

used to measure the intensity of light leaving a luminaire at various vertical and horizontal angles. This allows the photometric light distribution of the luminaire to be derived, and quantities such ...

The spectral types were estimated from the photometric light‐curve solution. Asymmetric light curves could be explained by assuming a cool spot on the secondary star. In the observing field of LZ Her, ...
