Here is a summary of the 5 bright star tests submitted as part of xcov18. I assume all the rest were. Thus the test is inconclusive. Cloud cut this run off but before it clouded over, the light curve looks fine. Light curve is fine.
Data are fine.
Either there are sensitivity drifts in the photometer or, most likely in my view, McDonald had a dusty atmosphere on that night. Ch2 shows similar but not perfectly correlated wobbles. Don Kurtz is also worried about this run but remarks that at 2600 muHz, the main frequencies in HR1217, the noise level is acceptable. I believe that, with attention to the issues raised, it is sensible to go ahead and schedule HR1217 for 2000 Nov. The McDonald data suffer from too much transparency variation, when compared with good data.
