Asteroid Catalog using AKARI IRC Slow-Scan Observations (Hasegawa+ 2013) ================================================================================ The Asteroid Catalog using AKARI IRC Slow-Scan Observations (version 1) Hasegawa S., Mueller T.G., Kuroda D., Takita S., Usui F. =2013PASJ...65...34H ================================================================================ ADC_Keywords: Solar system ; Minor planets ; Photometry, infrared Mission_Name: AKARI Keywords: catalogs - infrared: solar system - minor planets, asteroids - space vehicles: instruments Description: The Asteroid Catalog using AKARI IRC Slow-Scan Observations (AcuA-ISS) is the first asteroid catalogue produced based on the AKARI IRC Slow-Scan Observations. The catalogue provides the size and albedo of 88 asteroids. AKARI is the Japanese infrared astronomical satellite operated in 2006-2011. AKARI has carried out an all-sky survey in the mid- and far-infrared wavelengths, as well as thousands of pointed observations. The current catalogue was constructed from the data taken in the pointed observation mode with one of the onboard instruments, the IRC (Infrared Camera) at 9 and 18 {mu}m. An archive of IRC slow- scan observations comprising about 1000 images was used to search for serendipitous encounters of known asteroids.

HMAG and GPAR are the absolute magnitude and slope parameter taken from the Asteroid Orbital Elements Database of the Lowell observatory. NID gives the number of detections at S9W (9{mu}m band) and L18W (18{mu}m band) in total. DIAMETER and ALBEDO are the estimated size (diameter) and albedo, while D_ERR, A_ERR are their uncertainties estimated from the thermal model calculations (NEATM; Harris 1998Icar..131..291H). -------------------------------------------------------------------------------- History: * 7-Feb-2014: Documentation prepared at ISAS/JAXA by Sunao Hasegawa ================================================================================ (End) Sunao Hasegawa [ISAS/JAXA] 28-Apr-2014
