Dorado is a proposed space mission for ultraviolet follow-up of gravitational wave events. This repository contains a simple sensitivity and exposure time calculator for Dorado.

This package can estimate the signal to noise, exposure time, or limiting magnitude for an astronomical source with a given spectrum using the CCD signal to noise equation. It models the following noise contributions:

• Zodiacal light
• Airglow (geocoronal emission)
• Diffuse Galactic emission
• Standard CCD noise (shot noise, read noise, dark current)

To install with Pip:

$ pip install dorado-sensitivity

For examples, see the Jupyter notebook.

• Astropy
• Synphot for combining bandpasses and source spectra
• PyYAML for reading ECSV data files
