      Analysis

      Description

      3. A user can detect and analyze outliers I: SNR, PSF. [DES]
      i) Plot SNR vs. PSF FWHM at constant r.
      ii) Plot median r-band SNR in an aggregate quantity in bins of RA, Dec. Identify the bins with the 10% lowest SNR. Visualize the locations of these bins in the sky. Run some sort of auto-correlation, spatial covariance, or fourier-type analysis to look for patterns, particularly on the characteristics scales of a detector or focal plane.
      iii)
