Next: Gain steps Up: Additional information Previous: Measuring aperture . ... If the high voltage is changed to vary the gain, as is sometimes done in DC or CI work, the spectral response varies. This must be treated exactly like a variable measuring aperture: only data taken under constant conditions should be reduced together, but sometimes this can be done if adequate calibration data have been measured. The column label is PMTVOLTS. ...

... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...
