hp3d

Plot a HEALPix dataset on a 3D sphere

Contents

Syntax

h = hp3d(vPix,'Param1',Value1,'Param2',Value2,...);

Input Arguments

vPix   vector of values at HEALPix pixels
Param      Value
'nest'     vPix in nest index order (true | {false})

Return Arguments

h      (optional) array of patch handles for the sphere

Description

Let $f$ be a (real-valued) function on the sphere and vPix be a vector of function values at pixel $k$, $k=1\ldots12n_{\textrm{side}}^2$. hp3d(vPix,'nest',nest) plots the function on a sphere. The parameter nest indicates whether the values vPix are given in nested index order (true) or ring index order (false and default).

Example

plot nested pixel numbers on a sphere

hp3d(1:768,'nest',true);

Requires

corners, nPix2nSide
