Dec 2023, Stubbs & Urbach
| Goals | ||
|---|---|---|
| Upgrade DIMSUM- new lens, more sources, wider separation new mount- in progress | ||
| Dome and vent airflow measurements with wind speed sensor- Tues | ||
| Aux Tel dome slit vignetting tests vs. elevation angle. - needs engr time, no opportunity | ||
| Dream all-sky camera data access and analysis. Not accessible yet | ||
| Extinction tests with imaging data and with full-spectrum Aux Tel data. - Colin? | ||
Take | ||
DUMSUM2: Canon lens, new SD cards, battery eliminator, mechanical mounting parts, screws and bolt and fastners | ||

AstroChat demo
EFD pointing from DIMM?
Feb 12 2024 notes:
Figured out MOSS mount for AuxTel dome
action items:
Vent aux tel from 3 pm onwards
take calibration data in morning not evening, to keep dome open
do auto-expose during twilight
take sky flats, due to non-uniform pupil illumination
Clean exit window from white light source
