/* ascii output */
=== ascii output ===
The ascii spectrum contains the following columns, as labelled in the header:
'''wavelen objCounts skyAndBiasCounts'''
* If the file has been wavelength calibrated, the first column contains the wavelength in A, one line per pixel number. Otherwise the first column will be pixel number (i.e. just running number from 1 to Npixels).
* The second column is the counts in the extraction aperture after sky subtraction (if selected). Note: this is always '''summed counts within the aperture''', even if another extraction option (such as peak counts) is selected.
* The third column contains the '''counts per pixel''' from the sky aperture(s). If sky subtraction has been unselected, these will be 0.
