Notes. on surveys: Arecibo: single-feed data from O’Neil (2004). Arecibo AGES: multi-beam data, see Sect. 1. Arecibo ALFALFA α.40: multi-beam data with flux scale from Haynes et al. (2011). Arecibo ALFALFA old scale: multi-beam data from Haynes et al. (2011), corrected to the flux scale used in older ALFALFA catalogs (see Sect. 1). GBT: Green Bank Telescope single-feed data from O’Neil (2004). Nançay NIBLES: single-feed data, from the present paper. Parkes HIPASS: multi-beam data from, e.g., Meyer et al. (2004) and Wong et al. (2006).
