Domain_cfg in nemo 5 resulting a shift in cell

Hello,

I am migrating from nemo 3.6 to nemo 5.

  1. in my nemo 3.6 namelist, when i would specify:
    1. namelist:
      1. ppglam0 = -18.125 ! longitude of first raw and column T-point (jphgr_msh = 1)
        ppgphi0 = 30.1875 ! latitude of first raw and column T-point (jphgr_msh = 1)
    2. mesh_mask:
      1. nav_lon starting from: -18.125, -18.0625, -18,…
        nav_lat starting from: 30.1875, ….
  2. In nemo 5.0.1 when i want to generate domain_cfg using domain_cfg tool
    1. ppglam0 = -18.125 ! longitude of first raw and column T-point (jphgr_msh = 1)
      ppgphi0 = 30.1875 ! latitude of first raw and column T-point (jphgr_msh = 1)
    2. domain_cfg/mesh_mask:
      1. nav_lon starting from: -18.0625, -18, -17.9375,…
        nav_lat starting from: 30.25, ….

As there is a clear shift of one cell (0.0625) up in latitude and one cell right in longitude from the given coordinates, I changed my ppglam0 and ppgphi0 to one cell left and down to get same domain_cfg and mesh_mask in nemo 5.

I need to ask you that is this the correct way? or somehow nemo is doing something inside as this is something very easy to mistake with!
