MTA ACIS Rejected Events
The plots below are showing on-board rejected events.
The average EVTSENT, DROP_AMP, DROP_GRD, and THR_PIX obtained from L1 acis*stat1.fits
files are plotted for each observation. CTI observations (left) are plotted separately
from regular science observations.
- EVTSENT - number of events sent in data record
- DROP_AMP - number of discarded events due to corrected amplitude
- DROP_GRD - number of discarded events due to grade code
- THR_PIX - number of pixels above respective threshold level
