PROCEDURE: minjmin PURPOSE: Returns average value of j lowest-value points in the arrage. Works like min. INPUT: arr: multi-dimensional array KEYWORDS: dimension: dimension over which to find the min values (like in IDL min function) If present and nonzero, result is a slice, and output has 1dim less than arr If not present or zero, the min is found over the entire array and returns as scalar jmin_points: number of lowest value elements to average over (default=1, typical=3) CREATED BY: Vassilis VERSION: 1 LAST MODIFICATION: 10/08/29 MOD HISTORY: NOTES: Helper routine created to work with get_th?_pxxx.pro to remove ESA background contamination Idea is to average over a number of lowest count rate points to determine bgnd with improved statistics. $LastChangedBy: aaflores1 $ $LastChangedDate: 2014-01-24 15:20:50 -0800 (Fri, 24 Jan 2014) $ $LastChangedRevision: 14010 $ $URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/spdsoft/trunk/projects/themis/spacecraft/particles/ESA/packet/minjmin.pro $
