Date: Tue, 30 Sep 2008 11:45:24 -0700 From: Constance Rockosi Subject: Re: 2.5m obslog 20080929 (MJD 54739) This plate will not go quietly, will it. I've asked Craig and Steve about whether SoS really should be rejecting these -- we're back to the fact that SoS is looking at extinction-corrected magnitudes and we observe, of course, uncorrected magnitudes. Leave this plate off the telescope until they know what we've really got.
