Definition at line 531 of file constructCalibs.py.
|
inherited |
Generate the data identifier for the output calib.
The mean date and the common filter are included, using keywords from the configuration. The CCD-specific part is not included in the data identifier.
expRefList | List of data references at exposure level |

Interpolate over NANs in the combined image NANs can result from masked areas on the CCD. We don't want them getting into our science images, so we replace them with the median of the image.

Create and write an image of the entire camera.
This is useful for judging the quality or getting an overview of the features of the calib.
camera | Camera object |
dataId | Data identifier for output |
calibs | Dict mapping CCD detector ID to calib image |
Definition at line 874 of file constructCalibs.py.
|
inherited |
Process a CCD, specified by a data identifier.
After processing, optionally returns a result (produced by the 'processResult' method) calculated from the processed exposure. These results will be gathered by the master node, and is a means for coordinated scaling of all CCDs for flats, etc.
Only slave nodes execute this method.
cache | Process pool cache |
ccdId | Data identifier for CCD |
outputName | Output dataset name for butler |

Extract processing results from a processed exposure This method generates what is gathered by the master node. This can be a background measurement or similar for scaling flat-fields. It must be picklable! Only slave nodes execute this method.
Reimplemented in lsst.pipe.drivers.constructCalibs.FlatTask.
Definition at line 660 of file constructCalibs.py.

Process a single CCD, specified by a data reference Generally, this simply means doing ISR. Only slave nodes execute this method.
Reimplemented in lsst.pipe.drivers.constructCalibs.FringeTask, and lsst.pipe.drivers.constructCalibs.DarkTask.
Definition at line 637 of file constructCalibs.py.

Write the processed CCD.
We need to write these out because we can't hold them all in memory at once.
Only slave nodes execute this method.
dataRef | Data reference |
exposure | CCD exposure to write |
outputName | Output dataset name for butler. |

Construct a calib from a list of exposure references.
This is the entry point, called by the TaskRunner.__call__
Only the master node executes this method.
expRefList | List of data references at the exposure level |
butler | Data butler |
calibId | Identifier dict for calib |
Definition at line 422 of file constructCalibs.py.

Determine scaling across CCDs and exposures.
This is necessary mainly for flats, so as to determine a consistent scaling across the entire focal plane. This implementation is simply a placeholder.
Only the master node executes this method.
ccdIdLists | Dict of data identifier lists for each CCD tuple |
data | Dict of lists of returned data for each CCD tuple |
Reimplemented in lsst.pipe.drivers.constructCalibs.FlatTask.

Scatter the combination of exposures across multiple nodes.
In this case, we can only scatter across as many nodes as there are CCDs.
Only the master node executes this method.
pool | Process pool |
outputId | Output identifier (exposure part only) |
ccdIdLists | Dict of data identifier lists for each CCD name |
scales | Dict of structs with scales, for each CCD name |
dict | of binned images |
Definition at line 690 of file constructCalibs.py.
|
inherited |
Scatter the processing among the nodes.
We scatter each CCD independently (exposures aren't grouped together), to make full use of all available processors. This necessitates piecing everything back together in the same format as ccdIdLists afterwards.
Only the master node executes this method.

ccdIdLists | Dict of data identifier lists for each CCD name |
