I'm looking at post number 81 in this thread from Gerald and I don't understand the goal of the operation. I see color banding referred to, I'm assuming this is the post decompanded quantization artifacts? Is this from an operation referred to elsewhere?

Many Thanks.

That was an attempt to infer the decompanding function by correlating color channels. Later, the actual decompanding table was published, such that further attempts to infer the table from images became obsolete.

Does anyone have a link to the decompanding table? My Google fu is failing me.

Also do I understand things correctly that if I use the RDR data the de-companding is already done?

Thanks!

Appendix C in https://pds-imaging.jpl.nasa.gov/data/juno/...R_RDR_DPSIS.HTM

The RDR is decompanded, yes.
