mms.get_data returns wrong HPCA moments

Step 1: Latest code?

• [x] This issue is present in the most recent code (i.e. after running git pull this is still a problem).

Step 2: Describe your environment

branch: devel Matlab: 2021b Mac OS: 12.1

• [x] A 64-bit installation of Matlab was used.

Step 3: Describe the problem

The function "mms.get_data" with variable string 'Nheplusplus_hpca_srvy_l2' should return the number density of alpha particles (He++) but instead returns the number density of He+.

Same issue seems to be present with all He2+ HPCA moments. Burst or survey mode does not make a difference. Distribution functions seem to work as expected.

Using e.g., 'Nheplus_hpca_srvy_l2' returns the correct He+ density.

I checked the CDF file and the data there looks good. I would fix this myself but I am not familiar with how mms.get_data works.

Expected behavior

He2+ moments

Actual behavior

He+ moments

Steps to reproduce:

Tint = irf.tint('2018-01-23T08:00:00/2018-01-23T12:00:00'); Nhe2p = mms.get_data('Nheplusplus_hpca_srvy_l2',Tint,1)

The problem is here:

all_ions = {'hplus','heplus','heplusplus','oplus'};
ion_index = cellfun(@(s) ~isempty(strfind(Vr.param, s)), all_ions);
ion = all_ions{find(ion_index)};

ion_index = [0 1 1 0]: i.e.it returns 1 for both heplus and heplusplus and ion becomes the first instance. I can fix it.

Cecilia has fixed this issue. I'm closing it.
