ADC_Keywords: Photometry, UBV ; Clusters, globular Keywords: - BV photometry - horizontal branch Description: The BV photometric investigation of the Southern globular cluster NGC 1904 was carried out using the 1m telescope of Cerro Las Campanas (CARSO, 2 nights in February 1973 and 2 nights in April 1973), and the 1m telescope at la Silla (ESO, 4 nights in February 1975). The identification of the stars was made by B. Skiff (Lowell Obs.) in October 2010. File Summary:
