Lightcurve Fitting – Lightweight Enrichment Worker

This repository provides a lightweight version of Boom’s enrichment worker, focused on loading ZTF candidate data, computing basic photometric properties, and printing the results to the console. It is designed as a simplified environment for experimentation, debugging, and rapid iteration on light-curve metrics.

Running the project

All candidate JSON files should be placed inside a candidates/ folder. To process all candidates, simply run:

cargo run

This will:

• Load each .json file in candidates/
• Deserialize the ZTF candidate
• Compute the photometric properties
• Print all calculated metrics to standard output

Input data format

Each JSON file must contain a ZTF alert/candidate in the expected schema (same as Boom’s ZTF format).

Photometric analysis

The core computations are implemented in src/lightcurves.rs → analyze_photometry()

This function handles:

• Filtering photometry points
• Converting magnitudes
• Computing rising/fading rates
• Computing per-band properties
• Building AllBandsProperties and PerBandProperties
