Overview

7DT-Simulator is a Python package to simulate the expected photometric results for a given optical spectrum, taking into account the realistic sensitivity of the 7-Dimensional Telescope (7DT) system.

Main components modeled:

  • Optical throughput
  • Filter transmission curve
  • Atmospheric transmission
  • Camera quantum efficiency

The 7DT is a 20×0.5m telescope array in Chile with 20–40 medium-band filters, primarily designed to rapidly identify kilonovae — the optical counterparts of gravitational-wave events.

Installation

git clone https://github.com/SilverRon/7DT-Simulator
cd 7DT-Simulator/
pip install -r requirements.txt

Usage

See test/Example_7DT_Synthetic_Photometry.ipynb for a quick start example.

If you have a spectrum file with columns lam and flam, the simulator can convert it into synthetic photometry under realistic 7DT observing conditions.
