NICER XTI

NICER has ~21 ksec good data, taken between 2018-01-29 and 2018-02-23.  All 52 operating detectors were enabled.

Data were screened for undershoots in 0-40 ct/s/FPM range and overshoots in the 0-2 ct/s/FPM range, plus an additional cut on high energy X-ray counts (>2 keV, 0-4.5 ct/s/FPM cut).

This is a fit using the v2.11 model, only allowing the overall norm and NICER SCORPEON background terms to vary.

Image Added

The NICER norm is 0.993.  The backgrounds are pretty reasonable, although the "LEEL" background component would indicate a slightly rare condition.  Without "LEEL", the fit demands an additional high energy background component in the 2-10 keV range.

Using the v2.14 model, the NICER situation is considerable worse.

Image Added

NICER is not particularly sensitive to emission in the Fe K region.
