FORTRAN Generation
(/./ftp/cats/J/ApJ/591/138)

Conversion of standardized ReadMe file for file /./ftp/cats/J/ApJ/591/138 into FORTRAN code for loading all data files into arrays.

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 (1): Flag on counts 'f':
*    Upper limits are calculated for a confidence level of 90%, using either
*      a) equation (9) in Kraft, Burrows & Nousek (1991ApJ...374..344K)
*         for instances when the total number of counts in the
*         detection region is <=20, or
*      b) equation (3) in Gehrels (1986ApJ...303..336G), when the total
*         number of counts is >20.
*     The mean number of background counts was then subtracted from
*     these calculated upper limits.
*Note (2): The errors are
*          [{sigma}_T_^2^+{sigma}_B_^2^*(A_T_/A_B_)^2^]^1/2^
*    (e.g., Bevington & Robinson, 1992, Data Reduction and Error Analysis
*    for the Physical Sciences (2d ed.; New York: McGraw-Hill) p. 41),
*    where {sigma}_B_ are the respective 1{sigma} errors on the total 
*    and background counts, derived from equation (7) in Gehrels
*    (1986ApJ...303..336G), and A_T_ and A_B_ are the respective areas of
*    the source and background regions.
*Note (3): Corrected for Galactic absorption only, assuming that the source
*    is in NGC 1068 (distance = 14.4Mpc) and the emission is isotropic.
