add_dipole*
This routine provides a means to add a monopole and dipole to a HEALPix map.
Location in HEALPix directory tree:
src/f90/mod/pix_tools.f90
FORMAT call add_dipole*(
nside, map, ordering, degree, multipoles [, fmissval]
)
ARGUMENTS
| name & dimensionality |
kind |
in/out |
description |
|---|
| |
|
|
|
|
nside |
I4B |
IN |
value of
 resolution parameter for input map |
| map(0:12*nside*nside-1) |
SP/ DP |
INOUT |
HEALPix map to which the monopole and dipole will be
added. Those are added to all unflagged pixels. |
| ordering |
I4B |
IN |
HEALPix scheme 1:RING, 2: NESTED |
| degree |
I4B |
IN |
multipoles to add. It is either 0 (nothing done),
1 (monopole only) or 2 (monopole and dipole) |
| multipoles(0:degree*degree-1) |
DP |
IN |
values of monopole and
dipole to add. The monopole is described as a scalar in the same
units as the input map, the dipole as a 3D cartesian vector,
in the same units. |
| fmissval (OPTIONAL) |
SP/ DP |
IN |
value used to flag bad pixel on input
default:-1.6375e30. Pixels with that value are left unchanged. |
EXAMPLE:
call add_dipole*(128, map, 1, 2, ( 10.0_dp, 0.0_dp, 1.2_dp,
0.0_dp ) )
map is a HEALPix map of resolution
 , with the RING ordering scheme. A
monopole of amplitude 10 and a dipole of amplitude 1.2 and directed along the
y axis will be added to it.
