tabfi.F @ 1266

Last change on this file since 1266 was 1266, checked in by aslmd, 11 years ago

LMDZ.MARS
IMPORTANT CHANGE

Remove all reference/use of nlayermx and dimphys.h
Made use of automatic arrays whenever arrays are needed with dimension nlayer
Remove lots of obsolete reference to dimensions.h
Converted iono.h and param_v4.h into corresponding modules

(with embedded subroutine to allocate arrays)
(no arrays allocated if thermosphere not used)

Deleted param.h and put contents into module param_v4_h
Adapted testphys1d, newstart, etc...
Made DATA arrays in param_read to be initialized by subroutine

fill_data_thermos in module param_v4_h

Optimized computations in paramfoto_compact (twice less dlog10 calculations)
Checked consistency before/after modification in debug mode
Checked performance is not impacted (same as before)
