    v53 v54  
    2424 * Discussion about Heather's last results. See http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/ZoologyInvestigations2
    2525
    26  * 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; ''Detailed answers can be found there: http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/ZoologyInvestigations#AnswerstoA-014''
     26''Actions''
     27 * A-009 (See details): '''Done''' Answer Gene's questions:
     28   * 2) (Heather) What is the spatial distribution of these detections?
     29   * 3) (Heather) 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).
     30   (see http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/ZoologyInvestigations2)
     31 * A-012 (Roy): Build DS9 region files for "matched" detections with bad flags (see Heather for details, will help answering Gene's questions)
     32 * A-013 (?): Comments/Open Questions
     33   * 2) What has been missed from the Sloan detections?
     34 * A-014 (Serge) '''Done''' (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;
     35''Detailed answers can be found there: http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/ZoologyInvestigations#AnswerstoA-014''
    2736    * Assertion (1) is wrong. The FITFAIL flag can be set even if FITTED is not.
    2837    * CR_LIMIT is set. New question: Can it be used to filter out "bad" detections?
    2938    * Off-topic: the SIZE_SKIPPED meaning is the opposite of what is described in http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/CMF_PS1_V3
    30 
     39 * A-015 (?) Find out "good" cut-off values for true/false detections
     40 * A-016 (Serge?): Check if the detections found on flipped images are the flipped detections
     41 * A-017 (Heather): Ken's plots
     42 * A-018 (Serge): Rebuild the matching experiments
