J/PASP/114/298      BVI photometry in NGC 300               (Pietrzynski+, 2002)

Photometric standard stars in the BVI system in a wide field centered on the spiral galaxy NGC 300. Pietrzynski G., Gieren W., Udalski A. <Publ. Astron. Soc. Pac. 114, 298 (2002)> =2002PASP..114..298P

This sequence of standard stars is very useful for calibrating the photometry of variable stars and other objects in NGC 300 and other galaxies obtained from wide-field mosaic images. Our standard-star list contains B, V, and I measurements for 390 stars. The accuracy of the zero points in the V filter and B-V color is better than 0.02mag, and about 0.03mag for the V-I color. We found very good agreement between our measurements and those previously obtained by Walker for 26 stars near NGC 300. File Summary:
