Features in brief
- Basic information about the images or other FITS data, pixel statisitics.
- Conversion of FITS images to more easily presentable formats.
- Querying and modification of FITS header keywords.
- Calibration of raw images, including the masking of bad, saturated or otherwise unuseable pixels.
- Arithmetic operations on images, both on per-image and per-pixel basis.
- Combination of multiple images into a single one.
- Generic spatial geometric transformations of images (shifting, dilating, shrinking, clipping, higher order polynomial transformations, ...), including the registration of images to the same reference frame.
- Generation of artificial images.
- Detection and characterization of stellar profiles.
- Coordinate list manipulation (fit and evaluation of geometric transformations, point matching, pair matching, matching by identifiers, ...)
- Photometry (aperture, image subtraction, analytic profile modelling, PSF and various other sophisticated combinations of these).
- Regression analysis and general numeric data manipulation.
- Tasks are optimized for shell-level parallel processing.
