interpolate_bilinear_lonlat

astropy_healpix.interpolate_bilinear_lonlat(lon, lat, values, order='ring')[source]

Interpolate values at specific longitudes/latitudes using bilinear interpolation

Parameters:
lon, latQuantity

The longitude and latitude values as Quantity instances with angle units.

valuesndarray

Array with the values in each HEALPix pixel. The first dimension should have length 12 * nside ** 2 (and nside is determined automatically from this).

order{ ‘nested’ | ‘ring’ }

Order of HEALPix pixels

Returns:
resultfloat ndarray

The interpolated values
