    v20 v21  
    3232   c. then a single FOV was selected using extractcontrolnl: this passed QC and thinning and was the only FOVS in varobs; the FOV had a coordinates of 83.77021 degE, -28.4431 degN (N.B. !SatRad 1DVAR identified a cloud with CTP=686 hPa)
    3333
    34 5. Assimlated the single FOV using 3DVAR 
     345. Assimlated the single FOV using 3DVAR
    3535   a. following the changes in the Var_AnalysePF tasks of u-aj977 assimilated a single IASI FOV
    3636   b. a gridpoint nearest the FOV was selected: `cubes[2].coord('longitude').points[148]=83.53125` and `cubes[2].coord('latitude').points[164]=-28.3125`
     
    4444   a. this is easier as I don't need to run OPS task
    4545   b. chose IASI MetDB ch70 (temp Jacobian peaks at 143.84 hPa); there is a slight difference in resulting anal increment (why?) (glu_var_anal_n108 job 09)
    46    c. chose ch123 (temp Jacobian peaks at 610.60 hPa) (glu_var_anal_n108 job 11); the channel obs was not used (too close
    47 to the cloudtop?)
     46   c. chose ch123 (temp Jacobian peaks at 610.60 hPa) glu_var_anal_n108 job 11); the channel obs was not used by VAR (too close to the cloudtop?)
    4847
    49488. The chosen FOV has 91 used channels. Decided to pick another FOV with more used channels
