HOT-308 Optics Readme file Tully Rohrer **Note - cruise cancelled 12/11/18 as a result of safety issues - KM's A-frame counterweight cracked. Only optics deployments were the UW hyperpro and Kahe hyperpro casts. **LISSTs 1421 and 1285 were to be simulcasted again for another data comparison. With the cruise cancellation, this second comparison was scrapped and the sn1421 instrument was sent back to Sequoia for calibration. 12/6/18 Calibrated LISST with clean water ZSCAT. Took dark cals for FL3 and BBFL2. Checked batteries for DH4102 and LISST. Set clocks. Put LISST to sleep.
