wcsAlmostEqualOverBBox
(wcs0, wcs1, bbox, maxDiffSky=Angle(2.7777777777777779e06, degrees), maxDiffPix=0.01, nx=5, ny=5)¶ Test if two
WCS
are almost equal over a grid of pixel positions.Parameters:  wcs0 :
lsst.afw.geom.SkyWcs
WCS 0
 wcs1 :
lsst.afw.geom.SkyWcs
WCS 1
 bbox :
lsst.geom.Box2I
orlsst.geom.Box2D
boundaries of pixel grid over which to compare the WCSs
 maxDiffSky :
lsst.geom.Angle
maximum separation between sky positions computed using Wcs.pixelToSky
 maxDiffPix :
float
maximum separation between pixel positions computed using Wcs.skyToPixel
 nx :
int
number of points in x for the grid of pixel positions
 ny :
int
number of points in y for the grid of pixel positions
Returns:  wcs0 :
