• CsPad, cs140k: of all tiles of detector will exhibit a zero-photon peak, use common_mode=1, otherwise we recommend no correction (common_mode=0). It is also possible to request the use of the unbounded pixels by using common_mode=5
• Opal, Zyla: no common-mode correction. Should a pedestal of the correct shape have been produced, then it will be subtracted. common_mode=-1 will return the raw data.
• Jungfrau: no common_mode correction is the default.
• Epix: we are using a method called "common_mode=46" which removed pixels with a lot of signal (10x noise) and the neighbors. Then, the common_mode is calculated for reach row & column and then subtracted. This is similar to method 7 and different will be tested hopefully soon.

The common mode corrections are described <here> and DetObject simply wraps this.
