Exposure Time Calculator

We have developed Exposure Time Calculators to perform basic sensitivity calculations for the UVEX imager and long-slit spectrometer. These will initially be available as packages on GitHub, and we will be making a web interface available soon. 

  • Imaging ETC (currently imaging only; a basic spectroscopy simulator is coming soon)
  • ETC web interface (coming soon)

UVEX Response Files

The Exposure Time Calculator requires a dated set of UVEX response files (a CALDB) to function. You can download the latest version of the UVEX CALDB here:

Please note that this mission is still in development, and that this information reflects the current design but may not represent the final expected performance. We expect there to be multiple releases of the UVEX CALDB over time, so please check back for updates.
