Digital photographic photometry of NGC 5253

We give the B, V, R_B total magnitude of NGC 5253 obtained from digital surface photometry. The equivalent profile of this galaxy in the R_B₋band shows a strong exponential component originated in the disk. When compared with the V-profile shows a negative gradient in the color R_B-V analogous to th...
