Detailed Description

Task to run test stand data through eotest using a butler.

This task is used to produce an eotest report (the project's sensor
acceptance testing package)
Examples of some of its operations are as follows:
* Given a set of flat-field images, find the dark pixels and columns.
* Given a set of darks, find the bright pixels and columns.
* Given a set of Fe55 exposures, calulate the gain of the readout chain,
    in e-/ADU
* Given a set of Fe55 exposures, calulate the instrinsic PSF of the silicon,
    and the degradation of
* the PSF due to CTE.
* Given a set of flat-pairs, measure the photon transfer curve (PTC).
* Given a set of bias frames, calculate the read noise of the system in e-.
* Given a set of pocket-pumping exposures, find charge-traps in the silicon.

The RunEotestTask.runEotestDirect() is only applicable to LSST sensors, and
only for a specific type of dataset. This method takes a
dafPersistance.Butler corresponding to a repository in which a full eotest
run has been taken and ingested, and runs each of the tasks in eotest
directly, allowing for bitwise comparison with results given by the camera
team.

See http://ls.st/ldm-151 Chapter 4, Calibration Products Production for
further details regarding the inputs and outputs.

◆ __init__()

def lsst.cp.pipe.runEotestTask.RunEotestTask.__init__ (   self,

Constructor for the RunEotestTask.

Member Function Documentation

◆ makeEotestReport()

def lsst.cp.pipe.runEotestTask.RunEotestTask.makeEotestReport (   self,
  butler 
)
After running eotest, generate pdf(s) of the results.

Generate a sensor test report from the output data in config.eotestOutputPath, one for each CCD.
The pdf file(s), along with the .tex file(s) and the individual plots are written
to the eotestOutputPath.
.pdf generation requires a TeX distro including pdflatex to be installed.

◆ runEotestDirect()

def lsst.cp.pipe.runEotestTask.RunEotestTask.runEotestDirect (   self,
  butler,
  run = None 
)
Generate calibration products using eotest algorithms.

Generate all calibration products possible using the vanilla eotest implementation,
given a butler for a TS8 (raft-test) repo. It can contain multiple runs, but must correspond to
only a single raft/RTM.

- Run all eotest tasks possible, using the butler to gather the data
- Write outputs in eotest format

In order to replicate the canonical eotest analysis, the tasks should be run in a specific order.
This is given/defined in the "Steps" section here:
http://lsst-camera.slac.stanford.edu/eTraveler/exp/LSST-CAMERA/displayProcess.jsp?processPath=1179

But is replicated here for conveniece:
* 55Fe Analysis
* CCD Read Noise Analysis
* Bright Defects Analysis
* Dark Defects Analysis
* Traps Finding
* Dark Current                  X - will not be implemented here
* Charge Transfer Efficiencies
* Photo-response analysis       X - will not be implemented here
* Flat Pairs Analysis
* Photon Transfer Curve
* Quantum Efficiency            X - will not be implemented here

List of tasks that exist in the eotest package but aren't mentioned on the above link:
* linearityTask()
* fe55CteTask()
* eperTask()
* crosstalkTask()
* persistenceTask()

# TODO: For each eotest task, find out what the standard raft testing does for the optional params.
i.e. many have optional params for gains, bias-frames etc - if we want bitwise identicallity then we
need to know what is typically provided to these tasks when the camera team runs this code.
This can probably be worked out from https://github.com/lsst-camera-dh/lcatr-harness
but it sounds like Jim Chiang doesn't recommend trying to do that.
