Plot Averaging Modes
The Plot Averaging Mode describes how a
range of adjacent rows or columns are combined to produce a plot
showing a single line. Plot averaging works only for
Row and
Column profile plots in which the
image cursor is used to define the range of lines to
be averaged. The available averaging modes are described in the
table below.
Creating an Averaged Plot
-
Select the averaging mode from the
Averaging Mode menu. This selection
persists until you change it again.
-
Make the plot from the Horizontal or Vertical
plot menu or toolbar button.
As shown below, selecting an averaging mode (left
picture) inserts the specific command name into the plotting menu
(right picture). In this case, the Median averaging mode is selected, and the
Horizontal plotting menu shows the
Median Plot command.
The
Column and
Row Profile plots also allow you to change the plot
averaging mode. Below, the mode is set to Sum the adjacent
rows or columns into a single line of data:
Averaging Modes
Mira supports the following averaging modes:
Plot Averaging Modes
Mean
|
Calculates the arithmetic mean value of the
adjacent columns or rows.
|
Median
|
Calculates the median value at each point in the
adjacent columns or rows.
|
Sum
|
Adds the lines to make a single column or row that
is the sum of adjacent columns or rows. This method is often used
when extracting a spectrum from a 2-D image.
|
Std Dev
|
Combines adjacent lines to get the standard
deviation at each point along the line.
|
On the plot, the averaging mode that was used is
identified by the plot label (see
Plotting an Averaged Line).
