difmap

Description

difmap performs arithmetic operations or linear combinations over maps with the same resolution. difmap can display basic map information (resolution, maximum/minimum temperature values and positions), simple statistics: mean and variance, the histogram of pixel values of the map, and the number of pixels on a given temperature interval. difmap can also rotate the map in $\phi$ and/or $\theta$ direction, or convert the map from Galactic to equatorial coordinate base.

Examples

  1. Display statistics:

  2. Arithmetic operations:

  3. Map rotation:

  4. Masking:
