FORTRAN Generation
(/./ftp/cats/J/MNRAS/171/475)

Conversion of standardized ReadMe file for file /./ftp/cats/J/MNRAS/171/475 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 (1): The serial number of the 5C5 source is given in this column. The
*          sources in each survey are numbered in increasing order of right
*          ascension. Occasionally two sources are grouped together in the
*          lists, and given suffixes a, b; this is done either when there
*          are two peaks of emission at 1407 MHz but only one at 408 MHz, or
*          when there is an obvious association between the two sources. The
*          IAU nomenclature has not been adopted because this position-based
*          system would be ambiguous for some of the 5C sources which are
*          very close together. The authors recommend that when it is
*          necessary to refer to a source by its 5C name in a context in
*          which its position is not obvious, the 5C name should be
*          accompanied by the IAU name in parentheses, thus: 5C5.103
*          (0938+467).
*Note (2): These columns give the B1950.0 right ascension and declination of
*          the radio source. Positions measured at 1407 MHz are flagged with
*          an asterisk ('*') in the ext_flag column and are accurate to an
*          extra decimal place in right ascension and declination (2 decimal
*          places in RA and 1 in declination). For extended sources, the
*          position given is the peak of emission, the positional error
*          (pos_err) is listed as blank and 'ext_flag' is marked 'e'.
*Note (3): These columns give flux density information at 408 MHz. The flux
*          density is given in the S408 column. The rms uncertainty in the
*          408 MHz flux density is given in the e_S408 column, which
*          includes a contribution of 3 percent uncertainty in the envelope
*          correction.
*          The att_408 column gives the envelope attenuation
*          factor at 408 MHz (multiply S by this factor to recover S' and
*          hence the signal-to- noise ratio).
*          An asterisk in the f_S408 column indicates that the uncertainty
*          in flux density is very large because the source lies outside the
*          measured part of the envelope (attenuation factor less than 0.1)
*          These sources are included in the table only for their positions;
*          many of them have been observed in other surveys so it is
*          possible to check the positional accuracy.
*Note (4): These columns give flux density information at 1407 MHz. The flux
*          density is given in the S1407 column. The rms uncertainty in the
*          1407 MHz flux density is given in the e_S1407 column, and the
*          att_1407 column gives the envelope attenuation factor at 1407
*          MHz. An asterisk in the f_S1407 column indicates that the
*          uncertainty in flux density is very large because the source lies
*          outside the measured part of the envelope (attenuation factor
*          less than 0.15) These sources are included in the table only for
*          their positions; many of them have been observed in other surveys
*          so it is possible to check the positional accuracy.
*Note (5): This column gives the spectral index between 408 and 1407 MHz.
*          Alpha is defined in the sense S {prop.to} {nu}^-{alpha}^.
*Note (6): This column gives comments on the source. The following
*          abbreviations are used:
*
*             ARG   Half-Mile telescope Survey at 1421 MHz (Gillespie,
*                           1975MNRAS.170..541G)
