The Planck Early Release Compact Source Catalogue (ERCSC) includes nine lists of highly reliable sources, individually extracted at each of the nine Planck frequency channels. To facilitate the study of the Planck sources, especially their spectral behaviour across the radio/infrared frequencies, Chen et al. (2016) provide a `bandmerged' catalogue of the ERCSC sources. This catalogue consists of 15,191 entries, with 79 sources detected in all nine frequency channels of Planck and 6818 sources detected in only one channel.

To access this resource via TAP, issue ADQL queries on the table named ercscbm.
