+              v24
 Here is the list of problems in SAS9 (unresolved SA8 problems appended to the end)
+== To be fixed for SA10 ==
 || priority || problem                                                         || location || fixer || fixed? ||

 ||                || minor  zeropoint issue || ipp / ubercal || Gene/Eddie ||     ||
+||                || stackdetections some have kronflux = 0 and some have kronflux = -999 why? all things with forced photometry have kronflux = 0 (other columns are set to 0 as well - basically kron* and moments*  = 0) recommend they are set to null  || cmf file|| gene ||  ||
