Limiting Sensitivity Properties
All limiting sensitivity properties returned by the CSC 2.1 Quick search interface are calculated on a HEALPix grid with pixel size 3.22 arcsec from the Stacked Observation Detections Limiting sensitivity maps data products available through CSCview. These per-stack limiting sensitivity maps are calculated as described in Characterising CSC 2.1.
| Column Name | Type | Units | Description |
|---|---|---|---|
| ra | double | deg | ICRS right ascension of the location where the limiting sensitivity is estimated |
| dec | double | deg | ICRS declination of the location where the limiting sensitivity is estimated |
| flux_sens_b | float | ergs s-1 cm-2 | Estimated minimum energy flux in the ACIS broad (0.5-7.0 keV) energy band required for a point source to be detected and classified as MARGINAL at the detection position or at the query position and within the query radius |
