Do you remember the Viscacha that sometimes sneaks into our pupils? This is a problem when our mirror is uncalibrated, and the signal it sends to the pyramid wavefront sensor confuses our software. We get dark spots in the pupil (images of the secondary) that often look like our Viscacha friends. They got in back in our first commissioning run (see here and here), and took some Italian magic to deal with.
So today, after a long and frustrating alignment, we got started closing the loop on our calibration source and immediately went to war with the pupil viscachas. Simone was even calling for Truly Nolen at one point.
