ALMA Ceres Imaging and Spectrum

This archive package contains the calibrated imaging and spectral data, as well as the integrated photometric (lightcurve) data of Ceres at about 1 mm wavelength obtained from the Atacama Large Millimeter/submillimeter Array (ALMA) in October - November 2015, September 2017, and October 2017. The imaging data were collected with the ALMA 12-meter array in all three epochs with Ceres spatially resolved into about 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 were derived from the 12-meter images plus the ALMA Compact Array (ACA) data (effective frequency 259.39 GHz) obtained in the October 2017 epoch. The spectral data cover a frequency range of 256.636 - 266.136 GHz.
