"WebMar 21, 2024 · BVI photometry simply means that the brightness of the stars have been measured using three different filters - known as B, V and I filters. These filters have band passes of order 100-200 nm wide and are centred at around 450 nm, 550 nm and 850 nm respectively. The exact values will depend on exactly what filters are being used.
