NAME:
EXPAND_TILDE()
PURPOSE:
Expand tilde in UNIX directory names
CALLING SEQUENCE:
IDL> output=expand_tilde(input)
INPUTS:
INPUT = input file or directory name, scalar string
OUTPUT:
Returns expanded filename, scalar string
EXAMPLES:
output=expand_tilde('~zarro/test.doc')
---> output='/usr/users/zarro'
NOTES:
This version of EXPAND_TILDE differs from the version in the Solar
Library in that it does not call the functions EXIST and IDL_RELEASE.
However, it should work identically.
PROCEDURE CALLS:
None.
REVISION HISTORY:
Version 1, 17-Feb-1997, D M Zarro. Written
Transfered from Solar Library W. Landsman Sep. 1997
Made more robust D. Zarro/W. Landsman Sep. 2000
Made even more robust (since things like ~zarro weren't being expanded)

NAME: rotate_field_2_vec.pro
SYNTAX: rbsp_rotate_field_2_vec,'waveform','vec'
where 'waveform' and 'vec' are tplot variables
PURPOSE: Returns the input waveform or vector rotated to one of the following systems.
a) Min Var - input "vec" (e.g. DC Bfield) only
z-hat defined to be direction of "vec"
y_hat is given by vec cross x_max, where x_max is the maximum variance eigenvector
x_hat - max variance eigenvector always lies in x-z plane
Uses this system by default unless /efa is set or "vec2" is input
b) Two vec - input "vec" and "vec2"
z-hat is direction of "vec"
y-hat = (vec x vec2)/|vec2 x vec|
x-hat = (y-hat x vec)/|vec x y-hat| (vec2 is in x-z plane)
Uses this if "vec2" is set
c) EFA - similar to Two Vec, but doesn't require an additional input vector
z-hat is direction of "vec"
y-hat is the x-axis of input coord (roughly), formed by crossing vec
with [0,1,0].
Uses this if /efa is set
INPUT: Tplot variable names of:
waveform -> Name of tplot variable of [n,3] or [3] waveform data. Note that if the
Min var rotation is requested then must input a [n,3] where n>1
vec -> [n,3] element vector to represent the z-hat direction. Ex.
Bo in the coord system of "waveform".
Note that the coordinates of "vec" and "waveform" must be the same!
vec2 -> [n,3] (optional) element vector that will be used to determine the perp
direction ("Two vec" rotation only). The x-z plane will contain vec2.
Note that vec2 must be the same size as vec
NOTES: For EFA and Two Vec rotations, if "waveform" and "vec" have the same number of elements then
the rotations are vectorized and the program runs quickly. This doesn't work for the Min Var
rotation b/c "waveform" and "vec" cannot be the same size.
OUTPUT: Returns tplot variables of rotated waveform in requested coordinates
