The SW windows all behave the same. In particular there are only dark exposures and each of these exposures correspond to zero exposure times. The LW windows show different behavior, and also show differences amongst each other. Some details are discussed below.

The spectra in the two weird windows have high values for about 75% of the window but then drop to zero. It is not clear if the bright pixels actually contain good data points as the lines in the windows are weak, however I believe they do not contain good data. Note that the magnitude of the spectrum in the two windows is different by a factor of about 2.3. This is close to the difference in effective areas between the two wavelengths (factor of 2.2, with 279.80 being more sensitive).

In addition to the problems above, we also note that exposure 60 which is sandwiched between two missing exposures of the LW channel shows strange spectra.
