      Description

      A comment from the Ph.Gris's talk at the Lyon meeting (page 11) suggests that we should remove reference catalog sources that contain NaNs in relevant fields (e.g. centroid, shape, flux). We may want to do this in other SourceSelectors as well.

      Quoting the slide below for reference:

      [jointcal] Works fine, except for some cases where we get:
      jointcal INFO:    Chi2/ndof:    -­‐nan/478730=-­‐nan    
      jointcal INFO:    Chi2/ndof :    nan/485930=nan    
      jointcal INFO:    Chi2/ndof :    -­‐nan/447770=-­‐nan
      • This is not due to 
      jointcal itself but to some sources that have bad (nan) values for centroids sigma and/or for shape_xx/yy
      • Can be cured by modifying  
      astrometrySourceSelector.py in meas_algorithms
