The Parker Solar Probe (PSP) data is available in two coordinate systems, i.e., the interplanetary inertial coordinate RTN (Radial-Tangential-Normal) and the Spacecraft coordinate. I want to find the plasma wave signatures using the PSP data. Can anyone suggest which coordinate system will be best use for me in this regard?
Have you tried accessing NASA sites dedicated to this probe? The mission commander should have this information, or be able to provide it, if it doesn't interfere with security concerns.
I guess it depends on the wider context of your investigation. If you are looking at data from several instruments on SO then hopefully the data in SC coordinates puts all the data in the same frame (as opposed to different instrument frames) and so may be sufficient for a first assessment of this. If you are going to compare with other data sets, or need to interpret the data in a more global sense, then a heliophysics based coordinate system such as RTN may be preferable?
This is the answer from " Christopher John Owen " during the interaction in AGU Fall Meeting 2020.
