Class OldVlbaSourceCatalogReader

java.lang.Object
  edu.nrao.sss.model.source.parser.AbstractSourceCatalogReader
      edu.nrao.sss.model.source.parser.OldVlbaSourceCatalogReader

All Implemented Interfaces:

SourceCatalogReader

public class OldVlbaSourceCatalogReader
extends AbstractSourceCatalogReader

A parser of source catalog text files in the VLBA's format. Lines that start with "#" are comments. Data lines conform to this format:

 J2000 name IVS name  Right ascension  Declination     Pos_err X-band flux S-band flux C-Cat
                                                               Total Unres Total Unres
                      hr mn seconds    deg mn seconds    mas   Jy    Jy    Jy    Jy   
 

Whitespace is used as the delimiter. This parser does not count columns in order to find the next field, it just uses the whitespace. This means you may put any number of spaces between data items. Here is an example from the VLBA catalog:

 J1254+4536  1252+458  12h54m28.828654s +45d36'04.32606"  1.02  0.12  0.10  0.21  0.20  C-VCS1
 

For more detailed information about this format, see the VLBA Calibrator List.
