cogwheel.skyloc_angles¶

Coordinate transformations to and from right ascension and declination.

Functions

`cart3d_to_latlon`	Return latitude and longitude in radians corresponding to a Cartesian 3d vector assumed normalized to 1.
`cart3d_to_thetaphi`	Return spherical angles in radians corresponding to a Cartesian 3d vector r, assumed normalized to 1.
`get_rotation_matrix`	Return a rotation matrix R such that `R @ r = r'`, where `r'` are the coordinates in the new frame (@ is matrix multiplication).
`latlon_to_cart3d`	Return a unit vector (x, y, z) from a latitude and longitude in radians.
`lon_to_ra`	Convert longitude to right ascension.
`normalize`	Divide a vector by its norm.
`ra_to_lon`	Convert right ascension to longitude.
`thetaphi_to_cart3d`	Return a unit vector (x, y, z) from spherical angles in radians.
`x_rotation_matrix`	Rotation matrix about x axis in 3d space.
`z_rotation_matrix`	Rotation matrix about z axis in 3d space.
