PA2Measurement

class lsst.validate.drp.calcsrd.PA2Measurement(matchedDataset, pa1, bandpass, specName, verbose=False, linkedBlobs=None, job=None, metricYamlDoc=None, metricYamlPath=None)[source]

Bases: lsst.validate.drp.base.MeasurementBase

Measurement of PA2: millimag from median RMS (see PA1) of which PF1 of the samples can be found.

Parameters:

matchedDataset : lsst.validate.drp.matchreduce.MatchedMultiVisitDataset

pa1 : PA1Measurement

A PA1 measurement instance.

bandpass : str

Bandpass (filter name) used in this measurement (e.g., ‘r’).

specName : str

Name of a specification level to measure against (e.g., design, minimum, stretch).

verbose : bool, optional

Output additional information on the analysis steps.

job : lsst.validate.drp.base.Job, optional

If provided, the measurement will register itself with the Job object.

linkedBlobs : dict, optional

A dict of additional blobs (subclasses of BlobBase) that can provide additional context to the measurement, though aren’t direct dependencies of the computation (e.g., `matchedDataset).

Notes

The LSST Science Requirements Document (LPM-17) is commonly referred to as the SRD. The SRD puts a limit that no more than PF1 % of difference will vary by more than PA2 millimag. The design, minimum, and stretch goals are PF1 = (10, 20, 5) % at PA2 = (15, 15, 10) millimag following LPM-17 as of 2011-07-06, available at http://ls.st/LPM-17.
