Visual magnitude ranges from 9.7 to 19.4, and the B-V colour index varies from 1.15 to 1.97. The stars are grouped into 11 different fields, each of them is generally observable in a single CCD frame. The stars are located near Landolt UBVRI equatorial standards, accessible to telescopes in both hemispheres, and mainly within the 5 - 8 hours range of right ascension. Photometry, equatorial coordinates and finding charts are provided.9 p.application/pdfeng(c) The European Southern Observatory, 2000EstelsFotometria astronòmicaMethods: observationalTechniques: photometricStars: generalinfo:eu-repo/semantics/article164580info:eu-repo/semantics/openAccess
