Missing values for y-axis in spectrograms

[EvaKraemer]

I am not sure that here is the optimal place to raise this issue, but I don't know who I should contact about it.

I have been using the hapiclient to access and download data from the FPI instrument on the MMS mission. Some of the data is in form of spectrograms which is missing information on the values for the y-axis.

For example the energyspectrogram has the format (N, 32) with 32 being the number of energybins of the instrument. The instrument probes the plasma in the energy range 10eV - 30kev, however in the data downloaded from the hapiclient the information about the center-energy of each energy-bin is missing.

Here is some code illustrating the issue (note, the y-axis is only labelled from 0-32):

from hapiclient import hapi

server = 'https://cdaweb.gsfc.nasa.gov/hapi'
dataset = 'MMS1_FPI_FAST_L2_DIS-MOMS'
opts = {'logging': True,
'usecache': True}

parameters = 'mms1_dis_energyspectr_omni_fast'

t_start = '2015-11-14T09:00:00Z'
t_stop = '2015-11-14T10:00:00Z'

Get data

data, meta = hapi(server, dataset, parameters, t_start, t_stop, **opts)

from hapiplot import hapiplot
hapiplot(data, meta)

The original developer of the CDAWeb HAPI server put in the minimal amount of metadata. There is an upgrade in progress by SPDF/CDAWeb that would expose all of the information.
