Today we had to get up early for a 5 am compatibility test. This test resembles the final rehearsal for a theater play or a concert. It is used for testing that the payload can indeed be picked up by the CSFB (Columbia Scientific Balloon Facility) equipment, and that all electronic components can work in concert.
The mechanical parts of the instrument worked perfectly and the telescope pointed while being lifted by the CSFB crane. We did find some interference between several electronic components, one of which requires a hardware replacement which will be flown in tomorrow. Although we found an increased noise level in the focal plane detectors, our preliminary analysis indicates that the noise events can be filtered out at the analysis level. Our time schedule did not change: if the surface and stratospheric winds cooperate, we will launch the experiment this week, on Saturday or Sunday.
