COS
Target Acquisition Exposures

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.
