Detailed Description

Create a projected image based on a HEALPixSkyInstrument output cube.

This script creates a projected image based on the raw output of a HEALPixSkyInstrument.

The function takes the following arguments:

• inputFileName (string): the name of the file containing the raw HEALPix data cube
• outputFileName (string): the name of the generated projected image
• projection (string): the projection to use. Accepted values are Mollweide (for the Mollweide projection) and HammerAitoff (for the Hammer-Aitoff projection); default is Mollweide.
• nPixelX (int): Number of pixels in the vertical direction for the generated image. The number of pixels in the horizontal direction is twice this value. Default is 250.
• thetaCenter (float): Zenith angle of the central position relative to the original crosshair of the HEALPixSkyInstrument (in degrees). Corresponds to a vertical rotation that goes downward in the right half of the image. Default is 0.
• phiCenter (float): Azimuth angle of the central position relative to the original crosshair of the HEALPixSkyInstrument (in degrees). Corresponds to a horizontal rotation to the right. Default is 0.
