The CLASSIC data has a single object HD 222603 and Calibrator HD 220825. The calibrator diameter is 0.306mas. There may be one or more data files that are corrupt and will need to be removed from the final calibrated data. The diameter of the target should come out close to 0.576+-.067 mas.
The CLIMB data is for binary star 12 Boo, or HD 123999. The calibrator is HD 122364 and its diameter is 0.495mas. You should be able to fit a binary star to the final data with both stars unresolved and astrometry close to Rho= 0.91mas Theta = 1.32 degrees.
