| def lsst.skymap.detail.utils.coordFromVec | ( | vec, | |
defRA = None |
|||
| ) |
Convert an ICRS cartesian vector to an ICRS lsst.geom.SpherePoint
Parameters
----------
vec : `list` of `float`
An ICRS catesian vector.
defRA : `lsst.geom.Angle` or None
The RA to use if the vector is too near a pole;
ignored if not near a pole.
Raises
------
RuntimeError
If vec too near a pole and defRA is None.
| def lsst.skymap.detail.utils.makeSkyPolygonFromBBox | ( | bbox, | |
| wcs | |||
| ) |
Make an on-sky polygon from a bbox and a SkyWcs
Parameters
----------
bbox : `lsst.geom.Box2I` or `lsst.geom.Box2D`
Bounding box of region, in pixel coordinates
wcs : `lsst.afw.geom.SkyWcs`
Celestial WCS
Returns
-------
polygon : `lsst.sphgeom.ConvexPolygon`
On-sky region
