Functions

bin_spin_phases(spin_phases)

Bin spin phase angles into 4 quadrants: [315°-45°,45°-135°,135°-225°, 225°-315°].

compute_counts_by_charge_and_mass(...)

Compute the dust counts by charge and mass by spin phase or lon and lat per day.

compute_rates(counts, epoch_doy_percent_on, ...)

Compute the count rates given the percent uptime of IDEX.

compute_rates_by_charge_and_mass(...)

Compute the dust event counts rates by charge and mass by spin phase for each day.

get_science_acquisition_on_percentage(...)

Calculate the percentage of time science acquisition was occurring for each day.

get_science_acquisition_timestamps(evt_dataset)

Get the science acquisition start and stop times and messages from the event data.

idex_l2b(l2a_datasets, evt_datasets)

Will process IDEX l2a data to create l2b and l2c data products.
