+ * 
+ * The input array fluxLevels consists of Ni vectors, one per mosaic image.
+ * Each vector consists of Nj elements, each a measurement of the input
+ * flat-field image flux levels. All of these vectors must be constructed with
+ * the same number of elements, or the function will return an error. If a chip
+ * is missing from a particular image, that element should be set to NaN. The
+ * vector chipGains supplies initial guesses for the chip gains. If the vector
+ * contains the values 0.0 or NaN for any of the elements, the gain is set to the
+ * mean of the valid values. If the vector length does not match the number of
+ * chips, an warning is raised, all chip gain guesses will be set to 1.0, and the
+ * vector length modified to match the number of chips defined by the supplied
+ * fluxLevels. The sourceFlux input vector must be allocated (not NULL), but the
+ * routine will set the vector length to the number of source images regardless
+ * of the initial state of the vector. All vectors used by this function must be
+ * of type PS_DATA_F64.
