[Carpet] question about carpetregrid::activate_next (carpet stable 3)

[Bruno Giacomazzo]

Hi,
 	I'm using the third stable version of Carpet and I would like to 
activate at some fixed iterations new refinement levels. The idea would be 
to have a new refinement level at iteration=40000 and another one at 
iteration=70000.

 	I was looking to the description of the parameters in param.ccl, 
since there is no documentation, and my question is how 
carpetregrid::activate_next works. From what I have understood if I set 
for example

carpet::max_refinement_levels           = 5
carpetregrid::regrid_every              = 10000
carpetregrid::refinement_levels         = 3
carpetregrid::activate_levels_on_regrid = "fixed"
carpetregrid::activate_next             = 40000
carpetregrid::num_new_levels            = 1

 	then refinement level 4 will be activated at iteration 40000 and 
refinement level 5 at iteration 80000. Is it correct?

 	Is there a way to specify by hand a list of iterations at which 
the refinement levels should be activated? For example activate rfl 4 at 
it=40000 and rfl 5 at it=70000.

Thank you,
Bruno
