Hello,

according to the CalculationsPageOverview.pdf document, the exposure time set in the JWST ETC Detector Setup is simply

#groups x #exposures x #integrations. However, this is not the same as the time appearing on the left-hand side panel in the 'Calculations' window.

For example, for MIRI imaging I set groups=13; integrations=100; exposures=10. Then the expected integration time should be 13000 s. However, in the calculation I get time=36075s and a S/N ratio that presumably corresponds to this latter time (?).

Could you please clarify this?

Thanks,

Karina Caputi.
