Datatype: rosat

The ROSAT X-ray information has been split in two parts. The first one concerns the X-ray sources (position, count rate, exposure time, and so on) and is collected under the datatype: rosat_src.

The datatype rosat contains the information of the associated optical source.

The HR ratios are not based on the same energy intervals in all publications. It may be wise to check the energy band definitions.
