The VLA D and C array data of HCG 16 were collected by the Very Large Array (http://www.vla.nrao.edu/) in 1989 and 1999, under PI projects of Jacqueline van Gorkom and Marcus Verheijen. The project numbers are AW234 and AW500 respectively. The full original data of these projects are hosted by the VLA Archive (https://science.nrao.edu/facilities/vla/archive/index). In addition, there are two integrated spectra of HCG 16 from HIPASS (HI Parkes All Sky Survey, http://hipass.anu.edu.au/) and the Green Bank Telescope (Borthakur et al. 2010, ApJ 710, 385). This archive also includes a source mask to be used when CLEANing the HI line emission from the group and a separate mask identifying the region corresponding to each feature discussed in the coming paper Jones et al. (in prep.).
