Some of the PJ23 data are already available.

I'll start with a JPG version of several selected "pretty pictures". Colors are a white-balanced in an arbitrary way. The images went through several post-processing steps.

Image PJ23_18, approximately true color/contrast:



And with enhanced contrast/colors:





These images are interesting because of a very long haze band among other things. The band appears to cast a brownish shadow on the cloud deck below in the enhanced images. Below is an image where a stronger contrast stretch has been applied. The shadow is indicated with arrows; the haze band itself appears slightly brighter and bluer/whiter than the surrounding areas. Latitudes are planetographic and longitudes in system 3.



By the way I have noticed that for the PJ23 images I have needed to add a much smaller value to START_TIME than has been typical. I haven't processed a lot so far though (I have been concentrating on software development for increased automation and bigger accuracy when doing limb fits). It's possible that I've messed up which SPICE files I'm using although at first glance this didn't seem to be the case. The resulting images look perfectly normal despite this, i.e. good R/G/B alignment and nothing strange at the limb in map-projected images.

Mean and Stddev of my START_TIME adjustments for PJ23 are similar to other perijoves. (Using predict SPK since reconstructed isn't available yet).
