NAME ALMA Ceres Imaging and Spectrum V1.0
TYPE Data
DESCRIPTION This archive package contains the calibrated imaging and spectral data, as well asthe integrated photometric (lightcurve) data of Ceres at about 1 mm wavelengthobtained from the Atacama Large Millimeter/submillimeter Array (ALMA) in October -November 2015, September 2017, and October 2017. The imaging data were collectedwith the ALMA 12-meter array in all three epochs with Ceres spatially resolved intoabout 10, 15, and 15 beams, respectively, and have an average frequency of 265 GHz. Each epoch covers one full rotation of Ceres. The lightcurve data of Ceres werederived from the 12-meter images plus the ALMA Compact Array (ACA) data (effectivefrequency 259.39 GHz) obtained in the October 2017 epoch. The spectral data cover afrequency range of 256.636 - 266.136 GHz.
