I want to use the irfu-matlab package to analysis the PSP data. I am a novice in this field. I have no idea about how to start with the irfu-packages. I need help from the experts of this field. Your suggestions and help will be highly appreciated.

With best regards Krushna

Dear @Krushna-100,

I will try to answer a bit of your question as for how to get started with irfu-matlab. But please note that I have not written (or looked in detail at) the code in our specific PSPdevel branch as it is very much a work in progress and it is under active development. I suspect some of the contributors of this PSP specific code may be able to help if you have some more specific questions.

As for getting started you should:

  1. start Matlab (I assume you have a 64-bit install even though you did not tick this specific checkbox in our issue template).
  2. change directory to your local copy of irfu-matlab (its root folder).
  3. execute irf; to setup the required paths and environment.
  4. then to load PSP data specifically, I would point you to the function psp_load and its documentation/comments.

This psp_load function does appear to have some support for automatically downloading the PSP cdf files to a local copy on your machine if they are not present (may require some login) and then read them into our TSeries object.

Some examples how to read and plot the PSP data are here: https://gist.github.com/vaivads/b2dff623fef85e2a8d0a35331ce156c9

It's very much work in progress, so please notify of any problems.

Thanks
