  * A-009 (See details): Answer Gene's questions: 
-   * 1) (Serge/Heather for plots) What fraction of the detections have flux / flux_sig < 5 (the nominal cutoff) or < 3 (a possible agressive cutoff)?; 
    * 2) (Serge/Roy/Heather) What is the spatial distribution of these detections? 
    * 3) (Who?) What does the histogram of pixel value / sqrt(pixel variance) look like in areas / cells with large numbers of these detections?  Should be a Gaussian with a width of 1, but if there is excess noise from the camera in some areas, the width will be > 1 (we underestimate the variance).
- * A-010 (Roy): Is the false detections filter dependent?
- * A-011 (Roy/Heather for plots): Classify "matched": statistics similar to the unmatched (flags, flags2, flux_sig/flux ratio histogram, anything else)
  * A-012 (Roy): Build DS9 region files for "matched" detections with bad flags (see Heather for details, will help answering Gene's questions)
  * A-013 (?): Comments/Open Questions
    * 2) What has been missed from the Sloan detections?
-   * 3) Using the flags we cut about 2/3 of the good detections
  * A-014 (Serge) (1) Check if FITFAIL flag is set only if FITTED flag is set; (2) EXTERNALPOS, CR_LIMIT, SKY_FAILURE, SKYVAR_FAILURE, MOMENTS_SN should always be 0;
  * A-015 (?) Find out "good" cut-off values for true/false detections
