Sorry if this has been discussed anywhere but I can't seem to find much information about it - why is it that Voyager's pointing is so haphazard, as in this video of all the RAW Jupiter images - https://www.youtube.com/watch?v=bf5QJ8iFxUs?
I came across this link which says that pointing information for the images exists - http://pds-rings.seti.org/voyager/ck.html, but have also read on this forum that it's not very accurate. Would the information be useful in automatically aligning composite images and mosaics, or is it too coarse? Would it at least be useful in getting general alignments that could be refined by hand? And does anyone know why the cameras could not be pointed more accurately, or why accurate information could not be returned with the images? I assume it was some technical limitation, but just curious what it might be. |

Yes, they're type 1 kernels - they just have pointing information for when the images were taken Converting a type 1 CK kernel to type 2 is something I have regularly needed to do (I did it for most of the Voyager CK kernels). This is what I did with the Voyager 2 Neptune CK kernel file (and I used comparable parameters for Jupiter, Saturn and Uranus kernels): ckspanit -in vg2_nep_version1_type1_iss_sedr.bc -out vg2_nep_test_typ2.bc -typ 2 -tol 9000 |
