displayAstrometry
(refCat=None, sourceCat=None, distortedCentroidKey=None, bbox=None, exposure=None, matches=None, frame=1, title='', pause=True)¶ Show an astrometry debug image.
Parameters: - refCat :
lsst.afw.table.SimpleCatalog
reference object catalog; must have fields “centroid_x” an “centroid_y”
- sourceCat :
lsst.afw.table.SourceCatalg
source catalog; must have field “slot_Centroid_x” and “slot_Centroid_y”
- distortedCentroidKey :
lsst.afw.table.Key
key for sourceCat with field to use for distorted positions
- exposure :
lsst.afw.image.Exposure
exposure to display
- bbox :
lsst.geom.Box2I
bounding box of exposure; Used if the exposure is
None
- matches :
list
oflsst.afw.table.ReferenceMatch
List of matched objects
- frame :
int
frame number for display
- title :
str
title for display
- pause :
bool
pause for inspection of display? This is done by dropping into pdb.
Notes
- 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
