Attributes Documentation

adjustGridOption¶

Whether and how to adjust grid to fit evenly within, and cover entire: image (str, default 'spacing')

Allowed values:

'spacing': adjust spacing between centers of grid cells (allowing overlaps)
'size': adjust the sizes of the grid cells (disallowing overlaps)
'none': do not adjust the grid sizes or spacing
'None': Field is optional

borderSizeX¶: Dimensions of grid cell border in +/- x direction, to be used for generating expandedSubExposure. (float, default 5.0)

borderSizeY¶: Dimensions of grid cell border in +/- y direction, to be used for generating expandedSubExposure. (float, default 5.0)

cellCentroidsX¶: Input X centroids around which to place subimages. If None, use grid config options below. (List, default None)

cellCentroidsY¶: Input Y centroids around which to place subimages. If None, use grid config options below. (List, default None)

cellSizeX¶: Dimensions of each grid cell in x direction (float, default 10.0)

cellSizeY¶: Dimensions of each grid cell in y direction (float, default 10.0)

gridStepX¶: Spacing between subsequent grid cells in x direction. If equal to cellSizeX, then there is no overlap in the x direction. (float, default 10.0)

gridStepY¶: Spacing between subsequent grid cells in y direction. If equal to cellSizeY, then there is no overlap in the y direction. (float, default 10.0)

ignoreMaskPlanes¶: Mask planes to ignore for sigma-clipped statistics (List, default ('INTRP', 'EDGE', 'DETECTED', 'SAT', 'CR', 'BAD', 'NO_DATA', 'DETECTED_NEGATIVE'))

mapper¶: Task to run on each subimage (ConfigurableInstance, default <class 'lsst.ip.diffim.imageMapReduce.ImageMapperConfig'>)

reducer¶: Task to combine results of mapper task (ConfigurableInstance, default <class 'lsst.ip.diffim.imageMapReduce.ImageReducerConfig'>)

returnSubImages¶: Return the input subExposures alongside the processed ones (for debugging) (bool, default False)

scaleByFwhm¶: Scale cellSize/gridStep/borderSize/overlapSize by PSF FWHM rather than pixels? (bool, default True)
