barak.coord.ang_sep¶

barak.coord.ang_sep(ra1, dec1, ra2, dec2)[source]¶

Returns the angular separation in degrees on the celestial sphere between two RA/Dec coordinates.

Parameters :	ra1, dec1 : floats or arrays of floats, shape (N,) First set of coordinates in degrees. ra2, dec2 : floats or arrays of floats, shape (M,) Second set of coordinates in degrees.
Returns :	separation_in_degrees : array of floats, shape (N, M) If N or M is 1, that dimension is suppressed.
