lsst.afw.geom.skyWcs.SkyWcs.getRelativeRotationToWcs | ( | self, | |
otherWcs ) |
Get the difference in sky rotation angle to the specified wcs. Ignoring location on the sky, if another wcs were atop this one, what would the difference in rotation be? i.e. for otherWcs = createInitialSkyWcsFromBoresight(radec, rotation, detector) what is the value that needs to be added to ``self.rotation`` (or subtracted from `other.rotation``) to align them? Parameters ---------- otherWcs : `lsst.afw.geom.SkyWcs` The wcs to calculate the angle to. Returns ------- angle : `lsst.geom.Angle` The angle between this and the supplied wcs, over the half-open range [0, 2pi).

lsst.afw.geom.skyWcs.SkyWcs.pixelToSkyArray | ( | self, | |
x, | |||
y, | |||
degrees = False ) |
Convert numpy array pixels (x, y) to numpy array sky (ra, dec) positions. Parameters ---------- x : `np.ndarray` Array of x values. y : `np.ndarray` Array of y values. degrees : `bool`, optional Return ra, dec arrays in degrees if True. Returns ------- ra : `np.ndarray` Array of Right Ascension. Units are radians unless degrees=True. dec : `np.ndarray` Array of Declination. Units are radians unless degrees=True.
