UVEX, the UltraViolet EXplorer.

UVEX is a NASA Medium Explorer mission to map the transient sky in the ultraviolet, expected to launch in 2030. UVEX has a long-slit spectrograph and a 3.5° square field of view camera with two UV filters.

Note that the imaging mode exposure time calculator is a toy model based on the publicly available description of the mission from the UVEX science paper [1], and that roughly reproduces the public sensitivity plots. It will be replaced with realistic filter bandpasses when those are publicly released.

We make these simplifying assumptions:

• The filter bandpasses are Gassians that mimic the filter shapes on the UVEX web site.

• Assume that the PSF is critically sampled.
