LightCurveFiller

This is a data simulation tool designed to produce fake lightcurves with a similar sampling strategy to the real SO pipeline. The lightcurve data is then uploaded to the lightgest server.

Requirements

• go > 1.25.0
• github.com/google/uuid v1.6.0

Building

The application can be built using the golang toolchain:

go build cmd/main.go

This produces a binary, main. You can invoke this with ./main

Configuration

All relevant parameters can be configured using environment variables. By default, main will print the list of used parameters to the console. They are (note that dates default to the current date as 'end' and now minus one year for start):
