Description

The repository.zip file contains the JIRAM L band images of Io, Europa and Ganymede, as well as their tail (label _Tail). Each folder contains one folder for each orbit, which are called JM0XXX. The second-to-last digit of the folder name is the actual PJ number, except for the JM0003, which corresponds to PJ1. In each of the orbit folder there are .bmp images, labelled as RTH_Lxx_YYYY MMM DD hh:mm:ss-hh:mm:ss.bmp, where:

  • R is the orbit number. Please, remember that the JM0003 refers to PJ1, thus images beginning with '3H' corresponds to PJ1 as well.
  • T is the sub-phase of the orbit (likely not relevant).
  • H is the observed hemisphere.
  • Lxx derives from the JIRAM data indexing (not relevant).
  • YYYY MMM DD are the year, month and day of the observation.
  • hh:mm:ss-hh:mm:ss is the start and ending time of the observations. They coincide for the images in the Io, Europa and Ganymede folders, but not for the _Tail folders.

UPDATE: The fit_sph.zip archive contains the tabulated fit position of the footprint of Io, Europa and Ganymede derived from the images in repository.zip.  The first column is the System III longitude of the moon, while the last three columns represent the spherical coordinates of the auroral footprint. Units are degree and kilometre. The label "_Tail" marks the fit obtained with the position of the footprint tails; in these cases, the tables have only three columns for the position of the tail. 

The posbound.zip archive contains the tables of the position of the auroral features determined from the images in repository.zip. The time are given in UTC. The position (columns 8,9,10) and its upper and lower limits (columns from 11 to last) are in kilometres.
