IHW Comet 1P/Halley Infrared Photometry Description: Data fall into one of 3 cartegories: A. Standard IR photometrymagnitudes reporting: Filter Limiting Mag (when available) Magnitudes & error Aperture UT Time if Mid-observations Exposure time Airmass Chop Distance Chop Distance Offset distance & Direction Filter Set Notes B. IR Fluxes from KAO in Jy C. Addenda- IR data submitted after initial cutoff for archiving. Data from MLOF, WIRO, O’Brien Table 1: JD, time from Perihelion, r, delta, elongation, scattering angle, phase angle.. Table 2: date & time, magnitudes for each filter used Table 3: JD, r, delta, T_blackbody, T_color, Superheat, Max(lambdaF)lambda)) of IR, Max of scattered solar spectrum, albedo, BB angular size, nucleus radius, etc. Comments: Magnitudes No coments Fluxes No comments Addenda addenda. 2 Need a comment about zero-point of magnitude system?. – Hanner: This is in the Gehrz 2005 AJ 130, 2383-2391 and 1992 Icarus paper addenda.3 Revise Column 8 DESCRIPTION to read “Blackbody temperature for comet’s heliocentric distance” instead of simply “Blackbody temperature” Revise Column 10 DESCRIPTION to read "Superheat of the Continuum emission = T_color/T_Blackbody”
