Mira MX provides tools for calibrating images in world coordinates that report x,y position in spatial units such as mm, or microns, as
well as angular coordinates. Both pixel coordinates and world
coordinates are reported in displays, measurements, and plots. Also
provided is luminance calibration to report physical units such as
ergs/sec/cm2, Kelvins, or microliters.
- Live cursor in displayed images and plots reports world coordinates
if the image is calibrated.
- Interrogate, measure, and plot image data using either physical (world)
coordinates or pixel coordinates.
- The world coordinate calibration can be computed or assigned using linear
distance units or angular units of arcseconds. Mira MX also loads
world coordinates from images calibrated with such.
- Mira MX reports accurate, sub-pixel precision coordinates for
measurements of point sources, plots, and
fiducial points; angles, distance, perimeter, area, and point
luminance using pixel coordinates or calibrated world coordinates.
- The Interactive calibration tool uses a physical length and
user-specified distance to create a world calibration.
- Spatial calibration can be saved with the image.
