LASP-MIT Voyager Internal Discussions

LASP-MIT MOP Group Voyager internal discussions – these are not intended for external consumption but are posted here to document the process whereby we worked out how to re-analyze the Voyager PLS data at Jupiter.

2016-5-25 In pursuit of missing SSEDR data for Voyager 2 – here are some documents from Ralph: Voyager Memorandum 93,  Voyager Memorandum 125

2016-5-25 From emails related to the missing trajectory information…..

**From Fran: Voyager 2 we have a problem – For the following ranges we are missing SEDR information: missing  DOY 188.834 – 191.67 and 192-205.

**From Logan: So we’re looking at Vgr PLS data between 1979 Days 59-81 for V1 and Days 183-215 for Vgr 2. The data files that I have, which I believe have been processed from the raw SEDRs by someone at LASP, contain SIII position for Vgr around Jupiter and rotations from S/C Bus into PLS sensor coordinate frames. So as long as the 2nd one is there and there is some form of position for Vgr in the solar system, I think I need the following 2 files: v1_sedr_1979.001.00_1979.099.16.gz     v2_sedr_1977.232.16_1981.156.15.gz

**From John R: so the document you sent along was enough to figure out where these files originated, adam azabo made them, they run off the original sedr files, the fortran file that made them is in his directory
/nfs/carrington/h2/asz/traj    and is named  makessedr.f

**From John B: as far as I understand it adam made short sedr encounter tapes from the long ones, we have the program to do that from adam, but I am not quite sure we don’t have them already made.
