projected_distance#
- caput.astro.coordinates.spherical.projected_distance(ha, lat, dec, x, y, z=0.0)[source]#
Compute distance projected in the direction of a source.
- Parameters:
- haarray_like
The CIRS hour angle of the source in radians.
- latarray_like
The latitude of the observatory in radians.
- decarray_like
The CIRS declination of the source in radians.
- xarray_like
The East-West coordinate in wavelengths (increases to the East).
- yarray_like
The North-South coordinate in wavelengths (increases to the North).
- zarray_like
The vertical coordinate in wavelengths (increases upwards).
- Returns:
- distance
ndarray The projected distance. Has whatever units x, y, z had.
