reorder


This IDL facility allows the reordering of a full sky map from NESTED to RING scheme and vice-versa.


Location in HEALPix directory tree: src/idl/toolkit/reorder.pro


FORMAT

IDL> Result = REORDER (Input_map [, In=, Out=, N2R=, R2N=])


QUALIFIERS


Result
variable containing on output the reordered map

Input_map
variable containing the input map

In=
specifies the input ordering, can be either 'RING' or 'NESTED'

Out=
specifies the output ordering, can be either 'RING' or 'NESTED'


KEYWORDS


N2R=
If set, does the NESTED to RING conversion, equivalent to In='NESTED' and Out='RING'

R2N=
If set, does the RING to NESTED conversion, equivalent to In='RING' and Out='NESTED'


DESCRIPTION


reorder allows the reordering of a full sky map from NESTED to RING scheme and vice-versa


RELATED ROUTINES

This section lists the routines related to reorder


idl
version 6.1 or more is necessary to run reorder


EXAMPLE:

map_nest = reorder(map_ring, in='ring', out='nest')

The RING ordered map map_ring is converted to the NESTED map map_nest.
