 Dear Sir or Madam,
 I am currently working on problems including the evolution of the vector
 potential. With this I encountered some problems in setting up my
 simulations. Please allow me to state some of my observations:

 - The atmosphere reset routines are not scheduled all in their
 GRhydro_Avec version (e.g. the initial reset in CCTK_Initial)

 - Within the atmosphere reset routines, it is not made use of the
 GRHydro_Avec routines of variable conversion. (prim2conAM not used but the
 magnetic field ones)

 - The subroutine GRHydro_SqrtSpatialDeterminant is not always scheduled
 before the GRHydro_BvecfromAvec. Therefore NaNs are produced in
 GRHydro_BvecfromAvec.

 I do have further problems in GRHydro_CalcUpdate at the moment, however, I
 do not know yet where they lie. Please contact me, if there is interest in
 reviewing the GRHydro_Avec implementations. As I will use this option
 extensively, I will definetely be working further on this.

 My best
 Jens Mahlmann
