    2020 * In Fortran user code the pointer to the vector of inverse observation variances should be declared in the form[[BR]] `REAL, POINTER :: ivar_p_ptr(:)`[[BR]] It does not need to be allocated. The target vector has the length `dim_obs_p_diag`.
    2121 * If the observation diagnostics have not be activated by using [wiki:PDAFomi_set_obs_diag] the pointer will not be set and `dim_obs_diag=0` will be returned. This value can be checked before assessing the pointer array.
    22  * If the feature `thisobs%inno_omit` is used (see [wiki:PDAFomi_additional_functionality]), the inverse variance of the omitted observations will show the small value set by `inno_omit`. One can use this information to exclude such observations when analyzing differences between observations and observed ensemble.
     22 * If the feature `thisobs%inno_omit` is used (see the [wiki:PDAFomi_additional_functionality page Additional functionality of PDAF-OMI]), the inverse variance of the omitted observations will show the small value set by `inno_omit`. One can use this information to exclude such observations when analyzing differences between observations and observed ensemble.
