filterSources
Return to directory of Todd's tools
Reads a list of source coordinate positions and filters them to be within a specified box
on the sky, and writes those to a new file.
Usage:
tt.filterSources(myfile, blc, trc, outfile='', startline=41, startcol=7, endcol=31, writeCoordsOnly=False)
Inputs:
- myfile: an ASCII file containing source positions, e.g. from a journal electronic table
- blc: bottom left corner coordinate as a sexagesimal string
- trc: top right corner coordinate as a sexagesimal string
- startcol: the starting column from which to read the position string
- endcol: the ending column from which to read the position string
- startline: the first line in the file from which to start reading position lines
- writeCoordsOnly: if True, then only write the coordinates on each line (not the rest of the columns) to the output file
