Typo in ROPP FM/1DVAR UG

[Ian Culverwell]

Sec 5.9 of ROPP UG III says

The ropp_fm_bg2ro_2d tool also calculates bending angles with the 1D 
bending angle operator to enable comparison between the two forward 
models. ropp fm roprof2state is used to copy the level2a data
into a state1dFM structure. The 1D bending angles can then be 
calculated with ropp_fm_bangle_1d (Section 4.9).

It needs to spell out that it is the central profile of the slice that is forward modelled by ropp_fm_bangle_1d - not, as I read it, each profile in the section.

This had in fact already been done, at r4493. The ROPP FM UG now reads

The ropp_fm_bg2ro_2d tool also calculates bending 
angles with the 1D bending angle operator to enable
comparison between the two forward models. ropp_fm 
roprof2state is used to copy the centre profile of
the 2D section of level2a data into a state1dFM 
structure. The 1D bending angles are then calculated 
with ropp_fm_bangle_1d (Section 3.9). The resulting 
profiles are written into the ro_data%lev1b%impact_opt
and ro_data%lev1b%bangle_opt elements of the output 
ROprof structure.

Closing ticket as 'fixed'.
