Date: Mon, 10 May 2010 07:12:17 -0700 From: Daniel Eisenstein Subject: Re: 2.5m obslog 20100509 (MJD 55326) Hi, The asymmetry in the S/N between r1 and r2 in Cartridge 16 seems peculiar and worth investigating. Cartridge 13 had the opposite trend at a smaller level. Are these guider issues? Or a false signal from SOS?
