◆ fiducialMagnitudeLimit()
| lsst.pipe.tasks.computeExposureSummaryStats.ComputeExposureSummaryStatsConfig.fiducialMagnitudeLimit | ( | self, | |
| band, | |||
| pixelScale, | |||
| gain ) |
Compute the fiducial point-source magnitude limit based on config values.
This follows the conventions laid out in SMTN-002, LSE-40, and DMTN-296.
Parameters
----------
band : `str`
The band of interest
pixelScale : `float`
The pixel scale [arcsec/pix]
gain : `float`
The instrumental gain for the exposure [e-/ADU]. The gain should
be 1.0 if the image units are [e-].
Returns
-------
magnitude_limit : `float`
The fiducial magnitude limit calculated from fiducial values.
