/* 
 *  swharp_vectorB. 
 *
 *  Created by Xudong Sun on 8/22/11.
 *
 *  Modified by Monica Bobra to 
 *              -- include ALL spaceweather keywords in Leka and Barnes (2003, I and II)
 *              -- include potential field calculation from Keiji Hayashi
 *              -- run on los and vector data 15 april 2012 via sharp_functions.c
 *  Bz arrays
 *  Write out abs(B) as data segment and a few keywords as SW index
 *
 *  Use:
 *  First use the bmap module to create the in= and mask= parameters.
 *
 *  then run this module:
 *  swharp_vectorB "in=su_mbobra.bmap_fd10[401][2011.03.09_00:00:00_TAI-2011.03.10_03:00:00_TAI]" /

#	Content
1	/*
2	* swharp_vectorB.
3	*
4	* Created by Xudong Sun on 8/22/11.
5	*
6	* Modified by Monica Bobra to
7	* -- include ALL spaceweather keywords in Leka and Barnes (2003, I and II)
8	* -- include potential field calculation from Keiji Hayashi
9	* -- run on los and vector data 15 april 2012 via sharp_functions.c
10	* Bz arrays
11	* Write out abs(B) as data segment and a few keywords as SW index
12	*
13	* Use:
14	* First use the bmap module to create the in= and mask= parameters.
15	*
16	* then run this module:
17	* swharp_vectorB "in=su_mbobra.bmap_fd10[401][2011.03.09_00:00:00_TAI-2011.03.10_03:00:00_TAI]" /
