HiPERCAM exposure time calculator.


This form allows you to calculate HiPERCAM object counts, sky counts and signal-to-noise ratios on the WHT and GTC. The calculation is based on the measured HiPERCAM+GTC zero points for the us, gs, rs, is and zs filters.

The following assumptions are made:

If you don't know the SDSS magnitude of your target, you can use the formulae in Table 7 of Smith et al. (2002) to convert from UBVRI to ugriz magnitudes.
