Acknowledgement
UKS-IRM Prime Parameters, UKS/IRM High Resolution Data, or products derived from them may NOT be published or shown in any form without the consent of the Principal Investigators concerned. Acknowledgements to the PI and the UK CDHF would be appropriate in any published work; full-authorship may be required in some cases. Scientists intending to embark on studies involving AMPTE UKS/IRM data products are advised to contact the relevant Principal Investigator(s) early in order to ensure that the data is suitable for the study, that the project does not infringe on other ongoing work, and that the Principal Investigator in general consents to the intended use of the data. PIs can provide this support only on a best efforts basis, so please be as precise and succinct as possible, and please be patient when awaiting a PI response.

Caveats
The time tags represent the start times of accumulation intervals (spin). UKS times are UT stamped on board while IRM time stamps are UT at time of ground receipt. Thus for time-critical science, the IRM times need to be corrected by subtracting the light travel time from the spacecraft to the ground-station (at Weilheim in Germany apart special events requiring NASA DSN). For the transmission frequencies used, the vacuum light speed is appropriate. At apogee, this correction is more than a third of a second. There are no other known time delays.
