Following a bug reported by a CLASS user, it appeared that the
outputs from AVERAGE and ACCUMULATE in some exotic modes were incorrect. As
of the nov08 release of GILDAS, only the following
configurations were fully correct. These include the
default mode:
- ALIGN CHANNEL INTERSECT, WEIGHT TIME, BAD OR (default)
- ALIGN CHANNEL INTERSECT, WEIGHT SIGMA|TIME, any BAD
- ALIGN CHAN|VELO|FREQ INTERSECT, WEIGHT SIGMA|TIME, BAD OR
Other configurations (in particular the composite mode) may have
produced correct output, but with no waranty since it was depending on
the input spectra and the level of complexity of the combination. This
bug was affecting the default CLASS (i.e. CLASS90), but CLASS77 had a comparable level of bug for these commands.
This bug was fixed in the dec08 release of CLASS90, by fully
cleaning and factorizing the code. CLASS77 is not fixed according
to the policy concerning it: this package is obsolescent and is frozen
in order to keep a comparison point with CLASS90.
