Finding the nulls: work
from here
-
Make many plots of the field in x and
y at different heights above z
-
Match up nulls in
x and y that are probably a line in 3 dimensions
-
Compare the values of the z component
at these heights
-
If z component changes
sign then we have found a null
-
Assumes that value of z is not
a minimum or maximum at exactly Bz=0
-
Test programs
using contrived functions
-
Find out if correlation
between nulls and flares exists
