FUNCTION: mvn_swe_tabnum PURPOSE: Given a checksum, determines the corresponding table number. Only returns table numbers >= 3. The first two tables are rarely or never used. Six predefined tables are provided via keyword TABNUM. These correspond to tables as loaded into flight software. 1 : Xmax = 6., Vrange = [0.75, 750.], V0scale = 1., /old_def primary table for ATLO and Inner Cruise (first turnon) -64 < Elev < +66 ; 7 < E < 4650 Chksum = 'CC'X 2 : Xmax = 6., Vrange = [0.75, 375.], V0scale = 1., /old_def alternate table for ATLO and Inner Cruise (never used) -64 < Elev < +66 ; 7 < E < 2340 Chksum = '1E'X 3 : Xmax = 5.5, Vrange = [3./Ka, 750.], V0scale = 0., /old_def primary table for Outer Cruise -59 < Elev < +61 ; 3 < E < 4630 Chksum = 'C0'X GSEOS svn rev 8360 4 : Xmax = 5.5, Vrange = [2./Ka, 750.], V0scale = 1., /old_def alternate table for Outer Cruise -59 < Elev < +61 ; 3 < E < 4650 Chksum = 'DE'X GSEOS svn rev 8361 5 : Xmax = 5.5, Vrange = [3./Ka, 750.], V0scale = 0. primary table for Transition and Science -59 < Elev < +61 ; 3 < E < 4630 Chksum = 'CC'X GSEOS svn rev 8481 6 : Xmax = 5.5, Vrange = [2./Ka, 750.], V0scale = 1. alternate table for Transition and Science -59 < Elev < +61 ; 3 < E < 4650 Chksum = '82'X GSEOS svn rev 8482 USAGE: tabnum = mvn_swe_tabnum(i) INPUTS: i: The checksum or table number. KEYWORDS: INVERSE: Given a table number, return its checksum. $LastChangedBy: dmitchell $ $LastChangedDate: 2014-04-30 17:34:56 -0700 (Wed, 30 Apr 2014) $ $LastChangedRevision: 14990 $ $URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/spdsoft/trunk/projects/maven/swea/mvn_swe_tabnum.pro $ CREATED BY: David L.
