If you eis_prep on your data, then it automatically removes CRs with eis_despike unless the /nocr keyword is given.
If you are worried about whether real data are being flagged as CRs, then use the routine [eis_spike_viewer|EISSpikeViewer].
If you find an example where real data has been removed then please contact Peter Young.
! SAA periods
There are usually too many cosmic rays during SAA periods for the de-spiking routines to work effectively and so you should generally ignore SAA periods in your data. A possible exception is if you use very short exposure times, but this has not been checked.
If you worried about whether real data are being flagged as CRs, then use the routine [eis_spike_viewer|EISSpikeViewer].
