 Use the prepared [[en:praktikum:gdl|GDL]] scripts, which can be found at the [[en:praktikum:zugang |laboratory course computer]] (also see details of the [[en:praktikum:namenskonvention |name convention for files]]), to reduce the data photometrically. There are two scripts that do the principal data reduction (1_reduce_images.pro), the read-out, and the plotting of the photometry (2_obtain_flux.pro). Copy them to your local directory and adjust the names of the paths and the date of the current minimum. Compile and run the scripts with [[en:praktikum:gdl |GDL]] to obtain the light curve of the eclipsing binary star, which can be completed using archive data.  Use the prepared [[en:praktikum:gdl|GDL]] scripts, which can be found at the [[en:praktikum:zugang |laboratory course computer]] (also see details of the [[en:praktikum:namenskonvention |name convention for files]]), to reduce the data photometrically.
