Conversion of standardized ReadMe file for
file /./ftp/cats/J/ApJ/561/189 into FORTRAN code for reading data files line by line.
Note that special values are assigned to unknown or unspecified
numbers (also called NULL numbers);
when necessary, the coordinate components making up the right ascension
and declination are converted into floating-point numbers
representing these angles in degrees.

*Note (2): Apparent X-ray fluxes calculated by integrating the model spectrum
* over the energy range of the S2, M2 and H2 energy bands.
*Note (3): Intrinsic X-ray luminosity of the source in each of the three bands,
* correcting for the model NH absorption and assuming a distance
* of 7.2Mpc to M101.
