As Joseph reported yesterday, we couldn’t find any sign of our viscacha friends and we suspected it was due to the high winds and colder temperatures. Today I was able to gather more evidence. A correlation is seen between the local density of viscachas and the wind speed at their location. The following plot illustrates:

We establish a working threshold of 20 mph for vischacha absence. The nature of this transition is unknown.

It wasn’t all science today. We also fixed some calibration issues with our new setup in the LCO cleanroom. This took some remote help from our real-time software guru.
