The darkcurrent calibration is a technical calibration. It is not used to calibrate other calibrations or science data. The darkcurrent templates acquires a sequence of dark frames with different DITs and fits the relation current(DIT). While the darklevel retrieved from the dark recipe gives the dark counts in ADU for a master dark of a given DIT, the darkcurrent gives the current in ADU/sec in a more accurate manner.
