BVR Standardization of the CCD Photometric System of Chungbuk National University Observatory
BVR observations for 52 standard stars were performed using the 1-m reflecter with 2K CCD System of Chungbuk National University Observatory(CBNUO) in 2008. We obtained 1,322 CCD images to establish a correlation between our bvr system and the standard Johnson-Cousins BVR system. We derived the tent...

| Summary: | BVR observations for 52 standard stars were performed using the 1-m reflecter with 2K CCD System of Chungbuk National University Observatory(CBNUO) in 2008. We obtained 1,322 CCD images to establish a correlation between our bvr system and the standard Johnson-Cousins BVR system. We derived the tentative equations of transformation between then as follows;
V = v-0.0303(B-V)+0.0466
B-V = 1.3475(b-v)-0.0251
V-R = 1.0641(v-r)-0.0125
Using these equations the magnitudes in V, B-V, and V-R for 197 stars were obtained. |
