public class AsciiCatalog
extends PropertyBundles

This class reads an ascii-file and parses it to a list of star description. If any of the property keys is set, it corresponds to the column number and the length of the field. Each key should point to a pair of integers, the first giving the starting column, second the ending column (exclusive), or the length of the field, if the second number is negative. If no second int is given, the remainder of the string is used.

The standard fortran format used in most CDS descriptions differ from the normal column assignment. Subtract one from the starting column, leave ending column as-is.
