NAME: PSP_COMMON_SPC_INFO DESCRIPTION: Common variables used in PSP/SWEAP/SPC routines CREATED BY: Ayris Narock (ADNET/GSFC) 2020 $LastChangedBy: anarock $ $LastChangedDate: 2020-10-27 12:50:05 -0700 (Tue, 27 Oct 2020) $ $LastChangedRevision: 29302 $ $URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/spdsoft/tags/spedas_5_0/projects/SPP/sweap/SPC/L3i/misc/psp_common_spc_flaginfo.pro $

NAME: PSP_FILTER_SWP
DESCRIPTION:
Removed flagged values from PSP SWEAP SPC tplot variables based on selected
quality flags. See usage notes and available flag definitions by calling
with the /HELP keyword.
For each TVAR passed in a new tplot variable is created with the filtered
data. The new name is of the form: <tvarname>_{1,2,3}_XXXXXX
where each 'XX' is a 0 padded flag indicator sorted from lowest to highest.
So, psp_filter_swp,'np_fit',[3,4] results in tvar named "np_fit_3_0304"
Or, psp_filter_swp,'np_fit',0,status=2 results in tvar named "np_fit_2_00"
INPUT:
TVARS: (string/strarr) Elements are data handle names
OR (int/intarr) tplot variable reference numbers
DQFLAG: (int/intarr) Elements indicate which of the data quality flags
to filter on. Values from the set of integers 0 - 31
KEYWORDS:
HELP: If set, print a listing of the available data quality flags and
their meaning.
STATUS: (int) From the set {1, 2, 3}. Indicates which flag statuses will be
removed. (default = 3)
1: Remove only where the flag is explicitly marked as having
bad/problematic/condition present/etc
2: Remove (1) AND where status not determined ("don't know")
3: Remove all EXCEPT where explictly marked as
good/nominal/condition not present/etc for all selected flags
TODO: (what to do about the "don't care" encoding status?)
OUTPUTS:
NAMES_OUT: Named variable holding the tplot variable names created
from this filter. Order corresponds to the input array of tvar
names, so that tvar[i] filtered is in names_out[i]
EXAMPLE:
Keep only values explictly marked as good in the general flag
for the 'psp_spc_np_fit' variable
IDL> psp_filter_swp,'psp_spc_np_fit',0,status=3
Remove all values where flags 11 or 12 are explictly marked as bad
for the 'psp_spc_np_fit' variable
IDL> psp_filter_swp,'psp_spc_np_fit',[11,12],status=1

NAME: SIMPLE_GAPS
DESCRIPTION:
Find indices into an array such that when filtered on these
indices the resulting array has no more than one NaN value
in a row. The resulting array will not have a NaN in
the first or last element of the array, only as an in-between element.
Used in psp_dyplot to support properly iterating over data gaps when
plotting confidence intervals in piecewise fashion.
Expects data to be a 1D array.
INPUT:
DATA: 1D array to reference for non finite values
OUTPUTS:
KEEP: Integer array of indices to use to filter the data array.
EXAMPLE:
d = [6,4, !values.f_NaN, !values.f_NaN, 3, 1]
simple_gaps, d, keep_index = keep
d[keep]
--> [6,4, NaN, 3, 1]
