Parameters for solve_image.

Fields

ra_hint: f64

Approximate RA of image centre (radians, hint only).

dec_hint: f64

Approximate DEC of image centre (radians, hint only).

fov: f64

Image field of view along its longer side (radians). Used as the spiral step size, and, with the image’s size, for the pixel scale a solution is expected to have.

search_radius: f64

Maximum search radius from the hint position (radians).

quad_tolerance: f64

Quad ratio matching tolerance (ASTAP default ≈ 0.007).

hfd_min: f64

Minimum HFD for valid stars (pixels).

max_stars: usize

Maximum number of image stars to detect.

db_path: PathBuf

Path to the catalog directory.

db_name: String

Catalog name prefix (e.g. "d20", "d80").

binning: usize

Pixel binning factor applied before solving (1 = none, 2 = 2×2, …). WCS output is scaled back to original image pixel coordinates.

method: SolveMethod

Pattern-matching algorithm for the catalog spiral.

speed: SearchSpeed

Catalogue window per spiral position.

threads: usize

Worker threads for the spiral search. 0 = one per available core.

Spiral positions are independent, so they are evaluated a batch at a time across this many threads. Results are identical to the serial search: within a batch the lowest spiral index still wins, so the first position that verifies is the one returned, exactly as before.
