Method Detail

parse

public void parse()
           throws WavelengthArrayParseException

Parser of return stream from a StringReader, with data expected to be a pair of columns. The left column is wavelength values, the right column should be data values.

This is designed to be compatible with the HST STSDAS ttools tdump and tprint formats All comment lines beginning with '#' are ignored. The wavelength units must be in Angstroms, no units are assumed for the data values they will be stored as doubles.

Specified by:

parse in interface Wavelength1DArrayParser

Throws:

WavelengthArrayParseException - if there is any error in the parsing. No cleanup of the the dataset up to the point of the parse error is performed
