The proposed 4x4degree photometric calibration using the 1.3m telescope is so far unsuccessful. The June period was either cloudy or filled with smoke/ash from nearby forest fires. I am in a waiting pattern right now; another user of the telescope has priority until his project is completed. Hopefully I will be able to get back on the telescope before the monsoon hits (any day now).
ARNE is out of commission. As reported to Tom, the I-band camera broke one of the internal lenses, much as what happened with Tom last November. This occurred after January (the last use of ARNE) when we had a particularly cold spell. I am waiting for Tom to send a replacement telescope plus the upgrades that other Mark IV systems have (but ARNE does not, since it was an early model).
I am planning to revise the Tycho catalog used by Michael R. for photometric calibration to use the Bessell fits to improve the Ic transformation. I also expect to do a second test against Tycho2 to ensure the Bessell transformations are valid for that catalog (they should be, but it doesn't hurt to check). This revision should be available during July.
