Description
We present the comparison of the coronal visible light (VL) images obtained with the currently operating coronagraphs, such as Metis/Solar Orbiter, LASCO-C2/SOHO and COR2/STEREO-A. We compared the total (B) and polarized (pB) brightness data that was collected during various conjunctions and oppositions of these instruments in 2020-2023. Analyzing the latitudinal profiles of pB and B images obtained with each pair of coronagraphs, we found that they are in general highly correlated. As a result, we estimated additive and multiplicative scaling factors between these instruments.
