Zodiacal Light Data Investigation. Interim Results for the Earthlimb Clutter Experiment

Abstract

Zodiacal light data from the Earth Limb Clutter experiment (ELC) have been analyzed and compared with IRAS observations in order to bring the former into a common calibration framework with COBE and IRAS. There were 9 ELC spectral bands, 2 of which were broad (12 and 26 microns), and 7 of which were narrow (5.6, 9.6, 10.6, 11.5, 12.5, 13.7, 15.2 microns). The ELC data appeared to show considerable spectral structure in the zodiacal light for 9-15 micron regime. The recalibrated ELC data are also important because they contain zodiacal plane crossings at low (190) and high (1670) solar elongations -- regions not accessible to IRAS or COBE. The antisolar crossing is particularly interesting because it is associated with nearly symmetrically placed secondary peaks at + 280 ecliptic latitude. Possible origins for these peaks are discussed.
