Imaging Target Acquisition
Use this ETC to calculate exposure times for target acquisition exposures using ACQ/IMAGE mode.
"Dispersed Light" Target Acquisition
Use this ETC to calculate exposure times for target acquisition exposures using ACQ/SEARCH, ACQ/PEAKD, and ACQ/PEAKXD modes. Note that either a disperser or an imaging mirror may be used with ACQ/SEARCH, but that only dispersers may be used with ACQ/PEAKD and ACQ/PEAKXD.
Previous Calculations
Use this ETC to recall previous calculations, using the ETC ID number. Note all COS ETC ID numbers must include the preceding "COS" to recall a previous calculation.
