Detailed Description

Compute mask from statistic vs time/freq.

Base class for algorithms that compute a mask (set of chans/subints to zap) from a statistic (eg off-pulse variance or similar) as a function of time and frequency within an Archive.

Member Function Documentation

update_mask()

virtual unsigned Pulsar::TimeFrequencyMask::update_mask ( std::vector< float > &  mask, std::vector< float > &  stat, std::vector< float > &  model, unsigned  nsubint, unsigned  nchan, unsigned  npol  )

pure virtual

Update the mask.

mask is the current weights array. stat is the relevant statistic vs time/freq model is a model for how the statistic "should" look (ie a smoothed bandpass shape or similar).

mask is nsubint-by-nchan, stat and model are nsubint-by-nchan-by-npol

return value is number of points masked

Implemented in Pulsar::SumThreshold, Pulsar::InterQuartileRange, Pulsar::SortedMinimumSlope, and Pulsar::SetThresholds.
