25-step target for use with a Color Muse colorimeter

Click link to download a zip file containing a 25-step big-ass-squares step target appropriate for using when making measurements with the Color Muse colorimeter. This target has extra squares at 2.5% gray intervals for the first 10% and the last 10% of the scale - Wedgie can accept irregularly spaced values when reading the values from the Color Muse, and always outputs a standard 21-step file using some cubic spline interpolation techniques.
