@TJDOFLEARN –

I have a new version of the routine, and it largely follows the GitHub Issue that @foley.kristen pointed to you. I attached it here. You will need to change the file name to remove the “.txt” extension. You will also need to modify the Makefile to remove the compiling of ll2xy_lam_sec.f90 and ll2xy_lam_tan.f90.This code should be included in a forthcoming release.
