Apertide Star Profiles

Apertide is an offline star-profile inspector for iPhone and iPad. Import monochrome FITS frames, measure real candidates and take useful reports. MEASURE YOUR FRAMES Detect up to 300 brightest local maxima. Inspect half-flux radius (HFR) in input pixels, flux-weighted centroid, second-moment roundness and an encircled-flux curve. Adjust the aperture from 6–24 px and threshold from 3–15 sigma. Edge, crowded, flat-core, undersampled and aperture-limited candidates are flagged and excluded. Manually exclude other false detections. SEE THE FIELD A 3×3 mosaic shows the brightest accepted candidate in each region, its accepted count and the actual regional median HFR. Open the full-frame preview with candidate markers. Inspect any retained candidate's pixel crop and measurements. COMPARE AND KEEP Keep 12 local studies with up to eight equal-dimension frames each.
