Upload 2017-07-26: JunoCam Perijove 07 RGB Images of the Great Read Spot, Cropped Cylindrical Maps 180 Pixels Per Degree
The cylindrical maps are presumed to be cropped to between -30 and +30 degrees latitude planetocentric, and to between 230 and 250 degrees longitude west L3.
A pixel in the fully resolved maps corresponds to a square of an edge length of 1/180 degree, or 20''.
Geometric camera calibration and pointing is approximate. The residual error in unknown.
Color adjustment of the decompanded and linearized raw values is by relative linear radiometric weights of 0.82 for red, 1.0 for green, and 2.17 for blue, according to preliminary lab calibration.
This results in a greenish cast relative to "natural" appearence. A weight of 0.88 for red would have resulted in an appearence closer to "natural".
Color calibration is recommended to be considered tentative.

Cylindrical maps, 180 pixels per lon/lat degree, decompanded, color-adjusted, square-root encoded, assumed bad pixels patched as far as considered plausible.
Cylindrical maps, 180 pixels per lon/lat degree, decompanded, color-adjusted, approximately illumination-adjusted according to an undocumented ad-hoc heuristics based on solar incidence and emission angles, gamma-stretched to 4-fold radiometric values, assumed bad pixels patched as far as considered plausible.
Cylindrical maps, 180 pixels per lon/lat degree, square root of cosine of solar incidence angle.
