Some Question

[Zhugexiaoyuanyuan]

Hi, when I use the mms.psd_moments function, (I'm using the example you gave) I always get the following error: Traceback (most recent call last).
File "C:\Users\eric\AppData\Roaming\JetBrains\PyCharmCE2023.1\scratches\demo6.py", line 585, in
moments_e = mms.psd_moments(vdf_e, scpot, **options)
File "C:\anaconda\envs\pyrfu\lib\site-packages\pyrfu\mms\psd_moments.py", line 251, in psd_moments
field_name = vdf.attrs["FIELDNAM"]
KeyError: 'FIELDNAM'

from pyrfu import mms

tint_brst = ["2015-09-01T12:15:28.000", "2015-09-01T12:24:00.000"]

mms.download_data('pdi_fpi_brst_l2',tint_brst,1,data_path="C:\MMS\volumes")
scpot = mms.get_data("V_edp_brst_l2", tint_brst, 1)
vdf_e = mms.get_data("pde_fpi_brst_l2", tint_brst, 1)
options = dict(energy_range=[1, 1000])
moments_e = mms.psd_moments(vdf_e, scpot, **options)

Hi,
Thank you very much for reporting this issue!! The problem was due to changes in the structure of the VDFs (xarray.Dataset). pyrfu is continuously under development, so unspotted bugs can occur (although I do my best to test the code).

I fixed pyrfu.mms.psd_moments and uploaded the new release 2.4.9. The script is now running fine.
