- lsst.meas.astrom.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.
- refCat
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
