Data reduction and analysis
To date, the only data reduction performed has been the standard
procedures (bias subtraction, flat-fielding, and cosmic ray rejection) and
determination of spatial coordinates (from the position and position angle of
Jupiter). Questions of torus morphology can be addressed at this stage, but
subtraction of jovian scattered light and intensity calibration (from the disk
of Jupiter) must be performed for full analysis. Once this is performed,
we can use these data, the first synoptic imaging dataset of the Io plasma
torus, to address several important questions, among which are:
- An intensity peak in System III has been observed sporadically in the
past. Is it correlated with ribbon scale height, as would be epected if it
were related to ion temperature, or any other spatial feature?
- Does the radial position of the ribbon shift with System III
consistently?
- How long do longitudinal inhomogeneities persist?
- What effect (if any) does Io's phase have on the torus morphology?
- Does the System IV (10.225 h)
period in intensity variation appear? Is
it correlated with any morphological change?
