About the PDist format data #70

Closed zhang-chi-IGGCAS closed 12 months ago

zhang-chi-IGGCAS commented 3 years ago

Dear all., I found that using the PDist type data to plot the velocity distribution more conviently. but I want to know whether it is also valid for other mission data? e.g., Cluster and MAVEN. How to make the PDist data if I have the theta, phi and energy data? thank you!

Chi Zhang; Best wishes;

Dear @zhang-chi-IGGCAS,

sorry for the delayed reply. As I am not personally that familiar with the PDist function, and its limits and limitations, nor with Cluster & MAVEN data I am assigning this issue to @danbgraham who I hope can reply with a more details response.

As for the PDist itself, it does appear to have some construct support for thete, phi and energy data named "skymap", but I am not 100% sure if this is what you would have for other missions like Cluster and MAVEN. https://github.com/irfu/irfu-matlab/blob/c7204744a027f619a5c5f55327bc3ee9158f6a85/PDist.m#L57-L61
