Instrument team Science Operations Centers, SOCs, and/or Virtual Observatories, VOs, should facilitate this process serving as the contact point between PI and users in most cases. * 2) Users should heed the caveats of investigators to the interpretations and limitations of data or model results. Investigators supplying data or models may insist that such caveats be published. Data and model version numbers should also be specified. * 3) Browse products, Quicklook, and Planning data are not intended for science analysis or publication and should not be used for those purposes without consent of the PI. * 4) Users should acknowledge the sources of data used in all publications, presentations, and reports: "We acknowledge the NASA Parker Solar Probe Mission and the SWEAP team led by J. Kasper for use of data.". * 5) Users are encouraged to provide the PI a copy of each manuscript that uses the PI data prior to submission of that manuscript for consideration of publication. On publication, the citation should be transmitted to the PI and any other providers of data. Please acknowledge the Principal Investigator J.C.

TT2000 is measured in nanoseconds from J2000 with leap seconds included. Please refer to CDF TT2000 documentation with regards to this convention. This time corresponds to the first measurement of the spectrum. In accordance with SPDF standards, this epoch is interpreted a CDF_TT2000 time. It is acknowledged here that this epoch is not strictly equal to "terrestrial time" as it is defined in the CDF_TT2000 documentation nor is the calendar date interpreted by CDF_T2000 operation performed on this epoch strictly equal to Coordinated Universal Time, UTC. This Parameter exhibits an increasing Monotonic Progression.

For example, if the xxx_SUBSEC value is recorded in parts per 65536 o second, the correct procedure would be to round 50000*(xxx_SUBSEC/65536) to the nearest integer and cast a string by using the "I05" format. Here, CCSDS_MET is the mission elapsed time, in seconds, from the PSP Epoch, which is defined to be January 1, 2010, 12:00:00 UTC and xxx_SUBSEC is the elapsed time in fractional seconds since the last tick of MET typically in units of 2^-16 seconds.
