1st half - Engineering. DECal scan for filter N540 was successfully taken. There are still some problems with the flow of the refrigerant in the system. It required "manual" help (shake the cooling lines) to keep it flowing and maintain the temperature of the lamp within safe range. Javier and Hernan stayed at the DECal room, shaking the cooling lines, until the end of the scan. MANY THANKS!!! Scan ended at ~11:15pm and we started observing for the DELVE survey.
