correct_parallax(sr_xy, nbin, drt, alpha)¶
Adjust the geo-locations of the SR pixels
With SR, we refer to precipitation radars based on space-born platforms such as TRMM or GPM.
The sr_xy coordinates of the SR beam footprints need to be in the azimuthal equidistant projection of the ground radar. This ensures that the ground radar is fixed at xy-coordinate (0, 0), and every SR bin has its relative xy-coordinates with respect to the ground radar site.
