Notes from the 4PM Meeting¶
There is a way for observers to declare an exposure bad right after it’s finished. It should be used with caution, only on WF, and only after an earthquake.
DESDM: All received, including the backlog from yesterday. Processing is underway and is munching its way through last night. SN processing is not all finished.
SN DQ: so far the short fields are bad and the long fields are good. We’ll see what happens to X3z, though. Yes on the defocus procedure. Let’s keep lookin’ up and let’s be careful out there.
