Livetime corrections, integrated with datagaps, have been enabled for all of the hsi_spectrogram sub-classes, hsi_spectrum, hsi_lightcurve, and hsi_binned_eventlist.  Previously, it had only been enabled for binned_eventlist.  The new modules are in atest and will propagate at your next update.
 
There are no corrections for decimation yet.
