SUMMARY
The mean phase-weighted intensity magnitude of a variable star can be calculated by first converting binned magnitude data points into intensity values using the formula I = 10^(-0.4 * m), where I is intensity and m is magnitude. After obtaining the average intensity, the value can be converted back to magnitude using m = -2.5 * log10(I). The LEDA (Lyon-Meudon Extragalactic Database) is a valuable resource for accessing light curve data and additional information on variable stars.
