CFDT Photometric Indices
Please note: the Ca II K-line photometric data are a composite derived from CFDT1 and CFDT2 images. Composite Version 3.0 was adopted on May 19, 2009, replacing Composite Version 0.0. The new version affects all indices computed from Ca II K-line images, including Facular Area, Facular Excess, and K-line Excess.
