@esrivas17 @erik-17 Dear Professor, I would like to ask how many points should we choose when using the script gacos_operation.csh? I've seen references to sbas-insar processing with envi's SARScape and recommend choosing around 20 points, but can our gacos_operation.csh script accept multiple reference_points and run? Since our incidence_angle is calculated by reference_point, should we select the average of incidence_angle for multiple reference_points?

Hi, Yes, If you choose several points for establishing the reference then you should do it as well for the incidence angle and take the mean
