The test for BDF2 is in asgard_test and is labeled asgard_BDF2_test. When the test is run for fokkerplanck1_4p1a, it displays second-order accuracy and doesn't pass the test. If you run the commands
asgard(fokkerplanck2_6p1,'lev',4,'deg',5,'timestep_method','BDF2', 'dt',0.01,'num_steps',1, 'quiet', true);
asgard(fokkerplanck2_6p1,'lev',4,'deg',5,'timestep_method','BDF2', 'dt',0.0-5,'num_steps',1, 'quiet', true);
It does not give second-order accuracy.
