For all versions of GILDAS between oct19 and feb21
- Summing, averaging, or stitching spectra whose observing mode is
either position switching, wobbler switching, or unfolded
frequency switching gives the expected output spectrum.
- Summing, averaging, or stitching folded frequency switching
spectra could lead to slightly incorrect noise estimations in some
specific conditions.
- If the user is summing, averaging, or stitching all the
spectra in a single command, the output spectrum intensities and
their associated noise level are behaving as expected.
- Only when the user is summing, averaging, or stitching
folded frequency switching spectra in subsequent calls to
the AVERAGE, ACCUMULATE, or STITCH commands
would lead to incorrect noise levels. The shape of the line is
nevertheless preserved.
