The UV/IR paper is a nice comprehensive piece of work. I haven't really made any contribution, though, so you can leave me out of the et al. in the author list. I do have a comment. By lumping 10% calibration errors in with the IRAC measurements, I fear that you make them much less useful for many applications. First, any calibration error is likely to propagate from one band to the other, so it is not correct that there can be independent 10% errors - that is, it is not likely that the net uncertainty in an IRAC color difference measured to high nominal SNR could have a calibration uncertainty of 14% rms. Also, they claim a calibration accuracy of about 3%, I believe. Of course, there is the nasty problem of extended emission and scattered light at 5.8 and 8 microns, but in the two shorter bands smaller errors are appropriate, and it would be more useful if the reader could easily separate the calibration component from the statistical one. --After consultation with Tom Jarrett, the text has been revised to indicate that the IRAC flux calibration is 5-10% at 3.6 and 4.5 and 10-15% at 5.8 and 8.0.
