displayAstrometry()

def lsst.meas.astrom.display.displayAstrometry	(		refCat = None,
			sourceCat = None,
			distortedCentroidKey = None,
			bbox = None,
			exposure = None,
			matches = None,
			frame = 1,
			title = "",
			pause = True
	)

Show an astrometry debug image

- reference objects in refCat are shown as red X
- sources in sourceCat are shown as green +
- distorted sources in sourceCat (position given by distortedCentroidKey) are shown as green o
- matches are shown as a yellow circle around the source and a yellow line
    connecting the reference object and source
- if both exposure and bbox are None, no image is displayed

@param[in] refCat  reference object catalog; must have fields "centroid_x" and "centroid_y"
@param[in] sourceCat  source catalog; must have field "slot_Centroid_x" and "slot_Centroid_y"
@param[in] distortedCentroidKey  key for sourceCat with field to use for distorted positions, or None
@param[in] exposure  exposure to display, or None for a blank exposure
@param[in] bbox  bounding box of exposure; used if exposure is None for a blank image
@param[in] matches  a list of lsst.afw.table.ReferenceMatch, or None
@param[in] frame  frame number for ds9 display
@param[in] title  title for ds9 display
@param[in] pause  pause for inspection of display? This is done by dropping into pdb.

plotAstrometry()

def lsst.meas.astrom.display.plotAstrometry	(		matches,
			refCat = None,
			sourceCat = None,
			refMarker = "x",
			refColor = "r",
			sourceMarker = "+",
			sourceColor = "g",
			matchColor = "y"
	)

Plot reference objects, sources and matches

By default:
- reference objects in refCat are shown as red X
- sources in sourceCat are shown as green +
- matches are shown as a yellow circle around the source and a line
    connecting the reference object to the source

@param[in] matches  list of matches
@param[in] refCat  reference object catalog, or None to not plot reference objects
@param[in] sourceCat  source catalog, or None to not plot sources
@param[in] refMarker  pyplot marker for reference objects
@param[in] refColor  pyplot color for reference objects
@param[in] sourceMarker  pyplot marker for sources
@param[in] sourceColor  pyplot color for sources
@param[in] matchColor  color for matches; can be a constant
    or a function taking one match and returning a string
