Expand description

Full analysis result for an image.

Fields§

§width: usize

Image width (after debayer if applicable).

§height: usize

Image height (after debayer if applicable).

§source_channels: usize

Number of source channels: 1 = mono, 3 = color (after debayer).

§background: f32

Global background level (ADU).

§noise: f32

Background noise sigma (ADU).

§detection_threshold: f32

Actual detection threshold used (ADU above background).

§stars_detected: usize

Total stars detected before max_stars cap.

§stars: Vec<StarMetrics>

Per-star metrics, sorted by flux descending, capped at max_stars.

§median_fwhm: f32

Median FWHM across all measured stars (pixels).

§median_eccentricity: f32

Median eccentricity across all measured stars.

§median_snr: f32

Median per-star SNR.

§median_hfr: f32

Median half-flux radius (pixels).

§snr_db: f32

Image-wide SNR in decibels: 20 × log10(mean_signal / noise). Comparable to PixInsight SNRViews.

§snr_weight: f32

PixInsight-style SNR weight: (MeanDev / noise)².

§psf_signal: f32

PSF signal: median(star_peaks) / noise.

§trail_r_squared: f32

Rayleigh R² statistic for directional coherence of star position angles. 0.0 = uniform (no trail), 1.0 = all stars aligned (strong trail). Computed from detection-stage stamp moments on 2θ.

§possibly_trailed: bool

True if the image is likely trailed, based on the Rayleigh test. Uses configurable R² threshold (default 0.5) and eccentricity gate.
