Procedure:
goes_get_dist
Purpose:
Loads GOES MAGED and MAGPD data into standard SPEDAS particle structures
and returns pointer (or struct array) for use with goes_part_products
and spd_slice2d.
Calling Sequence:
data = goes_get_dist( probe=probe, datatype=datatype
[,trange=trange] [,index=index]
[/structure] [,/uncorrected] )
Input:
probe: probe designation, e.g. '15'
datatype: data type, 'maged' or magpd'
trange: (optional) 2-element time range, all loaded data used if not set
index: (optional) specify index/indices of sample(s) to return, supercedes trange
times: flag to return array of currently loaded sample times
structure: flag to return structure array instead of pointer to structure array
uncorrected: flag to use dtc_uncor data
Output:
return value: pointer to structure array (defualt)
structure array (/structure)
array of numerical times (/times)
0 - if error occurred

Procedure:
goes_part_products
Purpose:
Generate particle spectrograms for GOES MAGED/MAGPD data.
Data Products:
'energy' - energy spectrogram
'phi' - azimuthal spectrogram
'theta' - latitudinal spectrogram
'gyro' - gyrophase spectrogram
'pa' - pitch angle spectrogram
Calling Sequence:
goes_part_products, probe=probe, datatype=datatype [,trange=trange] [outputs=outputs] ...
Example Usage:
-energy, phi, and theta spectrograms
goes_part_products, probe='15', datatype='maged', outputs='phi theta energy'
-field aligned spectrograms
goes_part_products, probe='15', datatype='maged', output='pa gyro', $
mag_name = 'g15_H_enp_1'
-limit range of input data (gyro and pa limits do not affect phi/theta spectra)
goes_part_products, probe='15', datatype='maged', output = 'energy pitch', $
energy = [15,1e5], $ ;eV
pitch = [45,135]
Input Keywords:
probe: Spacecraft designation, '13', '14', or '15'
datatype: Data type, 'maged' or magpd'
trange: Two element time range [start,end]
outputs: List of requested outputs, array or space separated list, default='energy'
Valid entries: 'energy', 'phi', 'theta', 'pa', 'gyro'
energy: Two element energy range [min,max], in eV
phi: Two element phi range [min,max], in degrees, spacecraft spin plane
theta: Two element theta range [min,max], in degrees, latitude from spacecraft spin plane
pitch: Two element pitch angle range [min,max], in degrees, magnetic field pitch angle
gyro: Two element gyrophase range [min,max], in degrees, gyrophase
mag_name: Tplot variable containing magnetic field data for moments and FAC transformations
fac_type: Select the field aligned coordinate system variant.
Existing options: 'phigeo', 'mphigeo' (default), 'rgeo'
regrid: Two element array specifying the resolution of the field-aligned data
over a full sphere [n_gyro,n_pitch], default is [10,5]
suffix: Suffix to append to output tplot variable names
datagap: Setting for tplot variables, controls how long a gap must be before it is drawn.
(can also manually degap)
display_object: Object allowing dprint to export output messages
uncorrected: use uncorrected data
g_interpolate: interpolate uncorrected data
Output Keywords:
tplotnames: List of tplot variables that were created
get_data_structures: Set to named variable to return structures directly when
generating field aligned outputs. This may considerably
slow the process!
error: Error status flag for calling routine, 1=error 0=success
