Running ISIS with Dawn data

[oleg-alexandrov]

ISIS version(s) affected: 5.0.1

Description

I cannot spiceinit a Dawn mission cub file

How to reproduce

First I fetched the latest ISIS data as:

rsync -azv --delete --partial isisdist.astrogeology.usgs.gov::isisdata/data/dawn ~/projects/isis3data

then set up the ISISDATA value.

I verified that the desired kernels are where they should be (in this case, dawn/kernels/ik/dawn_fc_v10.ti).

Then I fetched the .IMG from PDS and tried to create the .cub file:

wget https://sbib.psi.edu/data/PDS-Vesta/Survey/img-1B/FC21B0004011_11224024300F1E.IMG.gz
gunzip FC21B0004011_11224024300F1E.IMG.gz
dawnfc2isis from=FC21B0004011_11224024300F1E.IMG to = FC21B0004011_11224024300F1E.cub
spiceinit from = FC21B0004011_11224024300F1E.cub

I get the errors:

Hi @oleg-alexandrov -- I think I've found the problem, but it's not yet clear to me why we're running into this problem. The TSPK found by spiceinit (isis_data/dawn/kernels/tspk/de421.bsp) does not include Vesta. I was able to run spiceinit with:

spiceinit from= FC21B0004011_11224024300F1E.cub TSPK='(/usgs/cpkgs/isis3/isis_data/dawn/kernels/tspk/sb_vesta_110211.bsp, /usgs/cpkgs/isis3/isis_data/dawn/kernels/tspk/de421.bsp)'

I'll continue looking into the problem on the spiceinit side, but in the meantime, you should be able to process dawn data by providing it with the necessary TSPKs.

I am experiencing a similar error:

Error = "No pointing available at requested time
[484127469.19564] for frame code [10101]"
End_Group
ERROR Unable to initialize camera model.

I understand I can solve it attaching the correct kernels, right? Do you know how can I identify the needed kernels by hand? I tried running the above command but does not work.

spiceinit from=FC21B0036778_15125195001F1F.cub TSPK='($dawn/kernels/tspk/sb_vesta_110211.bsp, $dawn/kernels/tspk/de421.bsp)'

Thanks

Hi, I just want to let you know that the solution did not work for Dawn mission data. Providing it with the necessary TSPKs does not work. After wasting a lot of time, the solution was installing Ubuntu 14.04 in a Virtual Machine, the old ISIS version and now it works. I run spiceinit without any problem. I think you should work on these data because people are wasting a lot of time on this issue. Thanks.

This was closed without an explanation. The explanation is here: #4684.

I can confirm that:

dawnfc2isis from=FC21B0004011_11224024300F1E.IMG to = FC21B0004011_11224024300F1E.cub target=VESTA

spiceinit from = FC21B0004011_11224024300F1E.cub

works (so, add target=VESTA), and the resulting images are usable with stereo. Now, creating a CSM file from .cub does not work, but that's a different story.
