The ACCUMULATE and AVERAGE commands perform many implicit features, and
perform silently non-trivial computations. When writing the current
document, the exhaustive check of all the combinations led to detect
two remaining bugs in the internal resampling loop.
These first configurations were incorrect:
In this case a spectrum with a better resolution was overweighted
during the resampling process by a factor
. This is not what user expects with an
- ALIGN VELO|FREQ COMPOSITE|INTERSECT, WEIGHT EQUAL,
any BAD, on spectra with different resolutions
These other configurations were also incorrect:
With this bug, no data available in one spectrum could be
synonymous of bad data in this spectrum. As a consequence a
piece of the output spectrum was wrongly flagged as bad with the
BAD OR contamination rule. This behaviour was different from
the other modes where no data available in one spectrum
implies to use data available in the other spectra.
- ALIGN CHAN|VELO|FREQ COMPOSITE, any WEIGHT,
These two bugs were fixed in the jul09 release of CLASS90.
