Darksift Master FITS

Prepare master-frame files from your own same-grid FITS images on iPhone and iPad. Darksift combines a selected batch into a real 32-bit floating-point FITS master. Compare a source, the master and a count map of excluded samples. Keep originals, settings and notes together for the next session. A NUMERIC WORKFLOW Choose Mean, Median or MAD mean. Mean and Median exclude no samples. MAD mean is one pass: values farther than your threshold × 1.4826 × median absolute deviation are excluded before an unweighted mean. The absolute rejection floor is 0.000001. Inspect exact source and result values at a one-based pixel coordinate. CONTROL THE INPUTS Import through native Files. Include or exclude a frame, remove it, add more or share an unchanged original. All included images must have identical dimensions.
