Fit one file and archive it

Prerequisites

Configure dust maps as described in Configure Galactic dust maps, and ensure the input contains RA, Dec, and redshift. For a controlled test, use an explicit E(B-V).

result = qsospec.fit_object_to_store(
    "spectrum.fits",
    "runs/my_object",
    redshift=1.2,
    galactic_extinction_config=qsospec.GalacticExtinctionConfig(
        ebv_override=0.0,
    ),
)

Expected outputs

The run directory contains a concise manifest, canonical Parquet datasets, and a main QA figure. Primary paths are available in result.output_files.

Common failures

Missing RA/Dec or map files: configure dustmaps or use ebv_override.
Existing run has a different configuration: choose a new run directory.
Reader detection fails: pass reader=... or inspect the file format.

Next: Inspect a run bundle and Render QA without refitting.
