pytomoatt.src_rec.SrcRec.geo_weighting

SrcRec.geo_weighting(scale=0.5, obj='both', dd_weight='average')[source]

Calculate and assign normalized geographical weights.

Source and receiver weights are normalized so that the maximum of each calculated population is one before weights are propagated to absolute and double-difference records. Consequently, all generated weights are no greater than one.

Parameters:

  • scale (float, optional) – Scale of reference distance parameter. See equation 22 in Ruan et al., (2019). The reference distance is given by scale* dis_average, defaults to 0.5

  • obj (str, optional) – Object to be weighted, options: src, rec or both, defaults to both

  • dd_weight – Weighting method for double difference data, options: average or multiply, defaults to average
