PROCEDURE: mvn_sta_dead_load PURPOSE: Loads dead-time arrays into apid common blocks for science data products, modified 20170919 for high background SEP events KEYWORDS: check: 0,1 if set, prints diagnostic data CREATED BY: J. McFadden VERSION: 1 LAST MODIFICATION: 15/03/02 MOD HISTORY: 14/12/20 changed algorithm to corrected valid events deadtime Deadtime = total(valid*dead,averaged)/total(valid,averaged) where "valid" are the valid events valid(energy,def) is extrapolated from apid c0 and c8 where "dead" is determined by rates dead(energy,def) is extrapolated from apid da and c8 dead calculation also uses apid d8 to determine relative amounts event types (see d1,d2,d3 in code) where "averaged" accounts for averaging over energy or deflection 15/01/17 added mcp droop correction 15/02/25 major modifications to mcp droop correction 17/10/02 major modifications to correctly account for background from SEP events NOTES: Program assumes that "mvn_sta_l0_load" or "mvn_sta_l2_load,/test" has been run Program requires c0,c8,d8,da packets are available at 4 sec cadence Program assumes Apids c2,c4,c6,ca,cd,cf,d3,d4 all have 4 second cadence If at some future date we are forced into slower cadence measurements, then code used for apid cc can be adapted to the above apids. TBDs ef3 should be made anode dependent to account for anode variations in anode rejection early in mission change code so that at attenuator transitions where count rates go below efficiency threshold, that the code will use the nearest attenuated values, not the higher attenuated efficiency. may have to break up the for-loop into 2 for-loops change code to default to anode efficiency based on anode rejection determination change code so that when background is high (as during deep dips from neutral density), the droop eff is properly calculated

PROCEDURE: mvn_sta_make_c6e PURPOSE: Makes common block structure mvn_c6e (64E-64M) from c6 (32E-64M) and c0 (64E-2M) data products CREATED BY: J. McFadden VERSION: 1 LAST MODIFICATION: 16/04/04 MOD HISTORY: NOTES: The common block can be accessed via mvn_sta_get_c6e.pro to return a single data structure Data structures can be operated on by programs like n_4d.pro, v_4d.pro Or used in conjunction with iterative programs such as get_4dt.pro and get_en_spec4dt.pro

PROCEDURE: mvn_sta_scpot_load PURPOSE: Loads scpot into static apid common blocks for science data products - only works if scpot is negative KEYWORDS: check: 0,1 if set, prints diagnostic data CREATED BY: J. McFadden 15/01/?? VERSION: 1 LAST MODIFICATION: 16/02/22 MOD HISTORY: NOTES: Program assumes that "mvn_sta_l0_load" or "mvn_sta_l2_load,/test" has been run Program will use some combination of sta, lpw, swe data to estimate scpot Assumption 1 - O2+ ram velocity only valid below 300 km Assumption 2 - low energy cutoff only valid when (Ni>100/cc and alt>180km) or in shadow Assumption 3 - when the above do not apply, s/c potential set to 0V TBDs - scpot is not valid 20151127/1:00UT - why is it invalid? TBD - cutoff keyword forces the use of c0 cutoff for potential - needed if winds impact potential
(See projects/maven/sta/mvn_sta_programs/mvn_sta_scpot_load.pro)
PROCEDURE: mvn_sta_scpot_update
PURPOSE: Overwrites STATIC spacecraft potentials with the
composite potential from mvn_scpot. Most of this
code is taken from mvn_sta_scpot_load.
This procedure generally does not affect STATIC-
derived potentials in the EUV shadow, since STATIC
is the primary source of potentials in this region.
It does provide better estimates in other regions,
replacing the STATIC-default 0 V with real estimates
in many cases.
INPUTS:
none: All information obtained from and written to common
blocks.
