readaometervig

The readaometervig function reads the pixel-wise vignetting calibration factor from from an \alpha\Omega-meter vignetting calibration file.

See:\alpha\Omega-meter

Usage:

[im,reso] = readaometervig(filename)

Where:

Parameter	Description
im	Is the return matrix contaning the pixel-wise vignetting calibration factor from a calibration file.
reso	Specifies the the matrix/image size.
filename	Defines the the file name and location. Note: An empty function call will open a popup menu for file selection.

Example:

Load ao-meter vignetting data and plot green channel correction factors:

[im,reso] = readaometervig('vignetting.cal');

imagesc(im(:,:,2))
axis equal off
colorbar
title('Pixelwise vignetting correction factor')
