Conversion of standardized ReadMe file for
file /./ftp/cats/J/ApJ/736/43 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): With an elliptical Gaussian ansatz for the unlensed image, there are
* twelve model parameters: six for the unlensed profile and six for the
* lensing transformation. The Gaussian parameters are combined into two
* real-valued variables, logS_0_ and {alpha}; and two complex variables,
* {theta}_c_ and {epsilon}. See section 3.2 for further explanations.
*Note (2): See equations 5, 17 and 18 and section 4.2 for further explanations.
