# Measurements of HS 1813+61 made at RIT Obs, Aug 4, 2005 UT, # made by Michael Richmond and Tracy Davis in poor conditions. # All data taken with 12-inch LX-200 + no filter + SBIG ST-8 CCD # no focal reducer, so at native f/10 # Each exposure 120 seconds long; tabulated times are midexposure # and accurate only to +/- 1 second. # 'mag' is a differential magnitude based on ensemble photometry # which has been shifted so USNOB1.0 1514-0236071 has mag=13.77 # (a rough guess = (B+R)/2 and the USNO B1.0 magnitudes). # # UT day JD-2,450,000 HJD-2,450,000 mag uncert Aug04.07340 3586.57340
