† An update on part_products library
- This is to announce that an important modification (see (1) below
for the details) has been made for the part_products library for
Arase particle data. In particular, the present update could affect
results of angular distributions of particle flux calculated with
part_products. It is highly recommended to update the ERG-SC
plug-in to the latest one (the r607_2019-01-08 version or newer).
(1) Implementing "no_ang_weighting" option
A new option "no_ang_weighting" has been implemented for
erg_???_part_products to suppress smoothing in solid angle
space of particle flux. As reported in the last ERG operation
meeting (@ISAS) on December 20, 2018, the current version of
erg_???_part_products automatically weighted-averages particle
flux values over ~10-20 degrees in solid angle, providing a much
smoothed angular distribution. The new option allows the users
to intentionally turn off the smoothing. A simple usage of the
option is as shown below.
(For pitch-angle spectra of MEP-e flux data, for example)
IDL> erg_mep_part_products, 'erg_mepe_l2_3dflux_FEDU', $
mag_name='erg_mgf_l2_mag_8sec_dsi', $
pos_name='erg_orb_l2_pos_gse', $
outputs='pa', energy=[10000.,20000.], /no_ang_weighting
