planck_colors
This IDL facility provides RGB color tables suitable for visualization of
sky maps dominated by CMB or featuring foreground, and modify current color
table.
Those color tables can then be implemented in
cartview,
gnomview,
mollview or
orthview and were used in Planck 2013 publications

FORMAT
QUALIFIERS
-
option
- required input for color
table generation, must be either 1 or 2:
1: creates the 'parchment' Blue-red color table suitable for maps
dominated by Gaussian signal (eg, CMB)
2: creates a Blue-red-white color table suitable for maps with
high dynamic signal (eg, Galactic foreground)
KEYWORDS
-
GET=rgb
- optional ouput, contains the newly created RGB color table
in a [256, 3] array
-
/HELP
- if set, prints extended help
-
/SHOW
- if set, the chosen color
table is shown in a new window
DESCRIPTION
planck_colors creates a set of RGB color tables suitable for specific purpose, and
modify the current IDL color table accordingly (using TVLCT). See below the example
applications. The created color table can also be output as a 256*3 array, or
shown in a new window
