 In addition to the code, the package contains preprocessed data in `data` directory. In particular, it contains ISGRI detector count rate cleaned from the contribution of X-ray point sources, for each INTEGRAL observation (so-called "science window", ScW) in the range of the INTEGRAL orbits 70-2740 and in different energy bands. This data set and code can be used to calibrate the ISGRI background model and measure the X-ray intensity of the Galactic background in different parts of the Milky Way.
 
+The preprocessed data will be continuously updated until INTEGRAL stops registering photons.
