    1616We have more carefully implemented the smoothing function and the code is now included in the ipp-trunk. There are several recipe values that now may be used to control the psphot kron measurements. Current defaault values are listed.

    18 * PSPHOT_APPLY_WEIGHT T apply gaussian weight of sigma == windowRadius
    19 * PSPHOT_APPLY_WINDOW T apply window function to downweight subtracted sources
    20 * PSPHOT_KRON_SMOOTH  F when true smooth the input image before measuring the kron radius
    21 * PSPHOT_KRON_SIGMA   1.7 smoothing parameter
    22 * PSPHOT KRON_NSIGMA  2 smoothing parameter
     18 * PSPHOT_APPLY_WEIGHT T apply gaussian weight of sigma == windowRadius
     19 * PSPHOT_APPLY_WINDOW T apply window function to downweight subtracted sources
     20 * PSPHOT_KRON_SMOOTH  F when true smooth the input image before measuring the kron radius
     21 * PSPHOT_KRON_SIGMA   1.7 smoothing parameter
     22 * PSPHOT KRON_NSIGMA  2 smoothing parameter

    2424Upon reviewing the following results the differences between applying the weighting and window functions are not significant. We suggest turning them off.
