The image is reprojected according to a slightly modified, and still preliminary geometrical camera model, cleaned from most repetitive camera artifacts and from most energetic particle hits, approximatly illumination adjusted, and stretched with gamma=4 with respect to radiometric values.

Applied camera geometry: pinhole focal length 1482.5 (square) pixels, Brownian radial distortion parameters K1=-6.0E-8, K2=3.0E-14, CX=809, CY=610.01, for all filters, relative to system with the following lower edge of readout regions: red 306, green 461, blue 616, left-most pixel column at x=0.

Juno rotation period=80.935 interframe delays, and roughly estimted to 30.063 sec, rotation phase of CCD around JunoCam's optical axis = 0.00153 radians relative to orthonormal frame defined by Juno's spin. Rotational angle around JunoCam's x-axis has been adjusted manually.

Geometry shift due to TDI has been neglected, as well as velocity aberration.

Assumed Jupiter shape model: 1 bar IAU Jupiter Maclaurin sheroid, rotating according to L3 longitude system.

Linear radiometric weights applied to decompanded colors: 0.88 for red, 1.0 for green, 2.17 for blue. Color interpolation is bilinear. Effects of global flat field and stray light have been neglected.

Resolution is 30 pixels per degrees in an equdistant cylindrical system centered to the camera at image stop time, with an axis parallel to Juno's spin axis. The rendered field of view is 60x180 degrees.
