Conversion of standardized ReadMe file for
file /./ftp/cats/J/A_A/569/A52 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): Notes as follows:
* * = indicates sources detected at <5{sigma} in 1.4GHz
* + = indicates sources with clear double lobe radio morphology
*Note (3): Positions from 1.4GHz VLA observations presented in Bondi et al.
* (2003A&A...403..857B) and Simpson et al. (2006MNRAS.372..741S).
*Note (4): Photometric redshift estimates taken from McAlpine et al.
* (2013MNRAS.436.1084M) and Simpson et al. (2012MNRAS.421.3060S,
* Cat. J/MNRAS/421/3060) for the sources in the B03 and S06 fields, respectively.
*Note (5): Spectroscopic redshifts taken from VVDS catalog (Le Fevre et al.,
* 2013A&A...559A..14L) and Simpson et al. (2012MNRAS.421.3060S,
* Cat. J/MNRAS/421/3060).
*Note (6): Spectroscopic redshifts, when available, are given preference over
* photometric redshifts to estimate the radio luminosities.
