- description
- This product, ION_MOMT_2007202_01.TAB, was originally released as part
of the PDS3 CO-S/SW-CAPS-5-DDR-ION-MOMENTS-V1.0 data set. The metadata
have been migrated to PDS4. The data themselves are unchanged.

- This is the first version of this product converted to PDS4. The DOI provided
references the PDS3 source data set.
Moments are generated from Cassini CAPS data and are partially
described in the CAPS guide for users found at the PDS web site:

- H+ density. Please note the difference between a
value of 0.000 and -1. The 0.000 corresponds to a
valid determination that is just extremely low (and
there is no confidence in the actual quantitative
value, other than that it is very low), whereas the
fill value corresponds to an invalid determination,
usually caused by problems in the integration
process.
