Blue Imaging Channel
High-cadence imaging provides important context information for the GFPI observations. Small-scale magnetic features are more more easily detected in particular wavelength regions, e.g., the Fraunhofer G-band. Furthermore, the broad Calcium H and K lines offer chromospheric diagnostics.
In 2016, new (faster) cameras will be integrated.
All BIC data (i.e., raw data and high-level data products) are stored in the GREGOR archive at AIP
