    v4 v5  
    55In the local filters (LESKTF, LETKF, LSEIK, LNETF) this routine gathers the full observation vector dimension from process-local observation vectors of size dim_obs_p and returns the full vector.
    66
    7 The routine depends on [wiki:PDAF_gather_dim_obs_f], which defines the process-local observation dimensions. Further, the related routine [wiki:PDAF_gather_obs_f2] is used to gather the associated rank-2 array of observation coordinates.
     7The routine depends on [wiki:PDAF_gather_dim_obs_f], which defines the process-local observation dimensions. Further, the related routine [wiki:PDAF_gather_obs_f2] is used to gather the associated rank-2 array of observation coordinates. 
    88
    99The routine is typically used in the routines [wiki:init_dim_obs_f_pdaf] and [wiki:obs_op_f_pdaf] if the analysis step of the local filters is parallelized.
     
    2020Notes:
    2121 * The routine `PDAF_gather_dim_obs_f` has to be called once before using `PDAF_gather_obs_f` because it internally initializes the local observation dimensions for gathering. The most recent call to `PDAF_gather_dim_obs_f` defines the dimensions `dim_obs_p` and `dim_obs_f` used here.
     22 * For cases with different observation types, the routine [wiki:PDAF_gather_obs_f_flex] can be used. It does not rely on `PDAF_gather_dim_obs_f` and is hence easier to use. It was introduced in PDAF 1.14.
