Meta Index / Home Page / Description

Caveats

lccorr is a complicated task and in its present form has not undergone a lot of testing. The attention of the user is directed in particular to the following caveats:

• The attitude is assumed to be stable throughout the duration of the time series. If this is not the case, the correction may be suspect.
• Loss of events due to pileup is not corrected. This effects worst bright sources with sudden spikes in emission.
• Timing and burst mode are not yet supported.
• For the present, spectral information cannot be supplied to lccorr. The task assumes internally a flat spectrum.
