healpy.projector.MollweideProj.vec2xy¶
- MollweideProj.vec2xy(vx, vy=None, vz=None, direct=False)¶
From unit vector direction to position in the projection plane (Mollweide).
- Input:
vx: if vy and vz are None, vx[0],vx[1],vx[2] defines the unit vector.
vy,vz: if defined, vx,vy,vz define the unit vector
lonlat: if True, angle are assumed in degree, and longitude, latitude
flipconv is either ‘astro’ or ‘geo’. None will be default.
- Return:
x, y: position in Mollweide plane.
