Band Contrast Maps: ebsd.props bc bs bands (What is the difference?)

[Zelda]

Hi Rudiger and Ralf,

When I check the properties of the ebsd i ve got

ebsd.prop
ans =

    bands: [122380×1 double]

       bc: [122380×1 double]

       bs: [122380×1 double]

    error: [122380×1 double]

      mad: [122380×1 double]

        x: [122380×1 double]

        y: [122380×1 double]

I plotted 3 of them in the same setting (same smothing etc)., here is the results

1. Would you tell me the difference of them, if all of them band contrast why they are in different intensity?

2. In prop I do not have IQ (Image quality), bu is there any way to plot ebsd.iq map. When I am plotting it, it gives me an error

plot(ebsd,ebsd.iq)
No appropriate method, property, or field 'iq' for class 'EBSD'.

Error in EBSD/subsref (line 40)

  [varargout{1:nargout}] = builtin('subsref',ebsd,s);

Many thanks in advance

Zelda

Hi,
wrt 1:
- bc is band contrast
- bs is band slope
- bands is the number of bands which were used to index this points
So these are different measures

wrt 2:
iq is a measure used on edax machines, your dataset seems to come from an oxford based software, so you won't have iq as far as I am aware of.

I hope this helps.
Cheers,
Rüdiger
