To: Voyager Colleagues Date: May 14, 1990 From: Ed Danielson Subject: Updated Calibration Factors for Voyager 2 Cameras Torrence Johnson and I discussed the accuracy of the last attempt to update the Calibration factors for the Voyager 2 Cameras from the "Danielson et al" paper. We were satisfied the figures given out on the 8/18/89 notes from Torrence were still the ones to use. However a final check showed that one of the blue filters was not converted correctly. Attached is a copy of the corrected calibration factors along with a copy of the "Danielson et al" paper. Happy Photometry!!
