     3This page documents the routine `PDAF_gather_obs_f`_flex of PDAF, which was introduced with PDAF V1.14.
     4
     5In the local filters (LESKTF, LETKF, LSEIK, LNETF) this routine can be used to gather the full observation vector dimension from process-local observation vectors of size dim_obs_p and returns the full vector.
     6
     7The 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.
     8
     9The interface is the following:
     10{{{
     11  SUBROUTINE PDAF_gather__obs_f_flex(dim_obs_p, dim_obs_f, obs_p, obs_f, status)
     12}}}
     13with the following arguments:
     14 * `dim_obs_p` : `integer, intent(in)`[[BR]] Process-local dimension of observation vector
     15 * `dim_obs_f` : `integer, intent(in)`[[BR]] Full dimension of observation vector
     16 * `obs_p` : `real, intent(in), dimension(dim_obs_p)`[[BR]] Process-local observation vector
     17 * `obs_f` : `real, intent(out), dimension(dim_obs_f)`[[BR]] Full observation vector
     18 * `status` : `integer, intent(out)`[[BR]] Status flag (0 for no error)
     19
     20Notes:
     21 * This is more flexible variant to the routine [wiki:PDAF_gather_obs_f]. It's functionality is the same, but it does not rely on a previous call to the routine `PDAF_gather_dim_obs_f`.
