| Abstract: |
The Exposure Time Calculator (ETC) is a tool to calculate either the signal-to-noise ratio or the exposure time of HST and JWST
observations. With a continuously evolving observatory like HST, maintaining this tool to support all available modes, which
use different types of detectors and different instruments, is a challenge. The calibration of modes is ongoing, which results in
instrument data updates, modification and enhancements to the underlying code, and integration of new modes, all while maintaining stability, robustness, and accuracy. In this poster we describe how this kind of tool is essential in the greater
scheme of preparing scientifically successful observations. |
