Error reading Rosetta/OSIRIS PDS3 image

[msbentley]

Opening the following Rosetta/OSIRIS PDS3 file (attached label):

https://pds-smallbodies.astro.umd.edu/holdings/ro-c-osinac-4-ext3-67p-m35-reflect-v1.0/data/img/n20160930t103106740id4bf32.img

I get the following:

In [2]: test = pdr.read('N20160930T103106740ID4BF32.IMG')

The same data product is also provided in FITS + LBL format:

https://pds-smallbodies.astro.umd.edu/holdings/ro-c-osinac-4-ext3-67p-m35-reflect-v1.0/data/fit/n20160930t103106740id4bf32.fit https://pds-smallbodies.astro.umd.edu/holdings/ro-c-osinac-4-ext3-67p-m35-reflect-v1.0/data/fit/n20160930t103106740id4bf32.lbl

which results in:

In [3]: test = pdr.read('N20160930T103106740ID4BF32.LBL')

Ok. I know what's happening. Will fix.

It's interesting that the same data product is provided as IMG and FITS.

[msbentley]

Great! Most of the glitches I find now seem to be related to pointers - should I hold off until this is addressed?

[cmillion]

Probably best. I'll need to carve out a few hours to dig into that. I hope to do it in the next few days.

[msbentley]

Fine by me - I really appreciate your efforts, and PDS3 data aren't going anywhere :)

[cmillion]

I appreciate your help, too! It's much easier for me to keep momentum with someone to iterate with.

[cmillion]

Ok. All of the weird pointers aren't necessarily supported now, but they are handled in a consistent way such that new pointers should not cause a raise. Unsupported pointers will print a warning note, though. Like "The ARCHIVE_CONTEXT_DESC pointer is not yet fully supported."

[msbentley]

Looks good, thanks!
