About numerical methods

Hi, everyone
I would like to confirm my understanding of these options and would appreciate it if you could point out my misunderstanding.

Time
do_mol = 1 # Use the MOL method

• mol_iters = 1 # First-order accuracy?
• mol_iters = 2 # Second-order accuracy?

do_mol = 0 # Use the SDC method

• sdc_iters = 1 # First-order accuracy?
• sdc_iters = 2 # Second-order accuracy?

Convection
The text mentions two PPM methods:

1. PLM:
   ppm_type = 0
   plm_iorder = 4

2. PPM + WENO:
   ppm_type = 1
   use_hybrid_weno = true
   weno_scheme = 1

The text mentions two mol methods:
mol_iorder = 1 or 2

But there doesn't seem to be any flag that determines whether I chose PPM or mol.
Is the mol method exclusively used for EB? Additionally, without using EB, is PPM the only method used by default?

CVODE
I noticed two types of cvode: GMRES and denseAJ_direct, which is more suitable for the detonation calculation？
