Skiff): In a series of papers in the A&A Supplements, Carrasco et al. provide very good UBVRI data for about 1000 stars. The stars are variously identified in the source papers, and are variously integrated into the General Catalog of Photometric Data (GCPD, see Cat. II/267). I have made a combined file showing HD numbers for the stars along with coordinates. The last two lists are available in VizieR (items J/A+AS/100/489 and J/A+AS/126/311). The GCPD shows all the papers, but for one it omits the VRI colors. The GCPD does usefully compute R-I colors, which are added here as well (Carrasco et al.give V-R and V-I). The stars are arranged in the order they appear in the papers, i.e. with the E-region standards first, then the general field stars. The authors calibrated their data consistently against Graham E-region standards. While adding the completed list to my comprehensive file, I noticed additional stars in common with the Cousins F-region standards, Landolt stars, and with GSPC stars (see Cat. II/272) observed in UBVRI at SAAO. These can all be considered as "pretty good" standards or secondary standards. The Carrasco data look especially good in this comparison, excepting the first paper with Moreno (1986A&AS...65...33M).
