AIP4Win v2.4.x is more powerful and more science-ready than ever before:

  1. Magnitude Measurement Tool (MMT) enhancements for stellar photometry.
    • Opens, calibrates, and runs photometry for time-sequence photometry.
    • Supports interleaved multi-filter (BVRI and Sloan) photometry.
    • Direct generation of AAVSO Extended and CBA format reports.
    • Raw photometry, instrumental magnitude, and data-dump formats.
    • Improved guide-star tracking for long time-sequence datasets.
  2. New Magnitude Extraction Tool (MXT) for stellar photometry.
    • Opens, calibrates, and runs photometry automatically.
    • Extracts magnitude data for every star for any number of images.
    • Optimized for variable star and exoplanet searches.
    • Extracts filtered magnitude data for color-magnitude diagrams.
  3. Support for Citizen Science photometry with DSLR cameras.
    • On opening, convert raw to green-channel grayscale images.
    • Automatic dark-frame and flat-fielding in photometry.
    • Output compatible with Citizen Science spreadsheets.
  4. Series Analysis Tool: Measure image statistics and image quality.
    • Measures sets of hundreds of images automatically.
    • Provides analysis of sub-exposures and time-sequence data.
    • Provides listing of whole-image stats (min, max, mean, median, etc.)
    • Tracks single pixel values for cold-pixel/hot-pixel diagnostics.
    • Tracks star FWHM, PeakPV, roundness, etc.  to assess image quality.
    • Automatically ranks image quality in 5 levels (---, -, 0, +, +++).
  5. Opens raw images from recent-model DSLR cameras.
  6. Improved processing for Bayer-array camera images.
    • Supports 16-bit raw Bayer-array images in FITS format.
    • Automatic de-Bayerization when stacking images.
    • Greater range of de-Bayerization options.
  7. Numerous changes and improvements to many processes.
  8. Reproducible software bugs reported by users are corrected.
