Polar CLEAN Strategies

  1. HSI_POLAR_CLEAN does not know about subcollimators or absolute spatial scales. It only knows :

  2. Advantages:

  3. The PSF consists of a 3-D array of   2-D HESSI Point-Spread maps, where

  4. After the map center is selected, the appropriate PSF array is read from disk (possibly after decompression).
    The array, which is of size 64 MB for maps of size 1024x128, is kept in memory during a CLEAN process.

    Advantages:

    Disadvantages:

  5. Examples:

  6. One may envision a PSF disk library may contain a wide variety of PSF arrays for all possible

  7. Disadvantages:
