tract7dt 0.1.2

7DT image-specific Tractor photometry pipeline

tract7dt

7DT image-specific Tractor photometry pipeline. This distribution is licensed under MIT.

Quick start

1. Install Tractor's prerequisites (see Tractor docs):

2. Install Tractor (from source or your preferred method).

3. Create a YAML config (see tract7dt/data/sample_config.yaml).

4. Run the full pipeline:

tract7dt run --config /path/to/config.yaml

Commands

• run: full pipeline (load → ePSF → patches → patch inputs → patch runs → merge)
• run-epsf: build ePSF only
• build-patches: build patch definitions only
• build-patch-inputs: build patch inputs only
• run-patches: run Tractor on patch inputs
• merge: merge patch results into final catalog

Notes

• The package preserves the reference behavior; changes are limited to packaging and path handling.
• Tractor and astrometry.net must be installed separately.
• Python prerequisites like numpy and scipy are included in dependencies; optional extras (eg fitsio, emcee) are included for safety.
• Input images are provided via a text file (one FITS path per line).
• Parameter mapping reference: docs/CONFIG_MAPPING.md.
