数据描述

This dataset comprises ALMA (Atacama Large Millimeter/submillimeter Array) observations spanning multiple projects, including studies of debris disks, gamma-ray bursts, asymptotic giant branch stars, and active galactic nuclei, with a total of 96,313 observations across 5,586 projects. It contains 157,548 spectral lines from molecules such as CO, HCO+, CS, HCN, and H2O, observed over frequency ranges from 100 to 900 GHz. The data include detailed parameters for each source, such as coordinates, band, continuum sensitivity, angular resolution, velocity resolution, and integration time, with metadata on project codes, principal investigators, and publication references. This collection supports research into star and planet formation, stellar evolution, and galaxy evolution.
