= PDAFomi_check_error =

This page documents the routine `PDAFomi_check_error` of PDAF. The routine was introduced by PDAF version 2.2.

The routine returns the value of the PDAF-OMI internal error flag. Since PDAF-OMI executes internal routines in which errors could occur due to an inconsistent configuration of the observations a directly returning an error flag as a subroutine argument is not always possible. For this reasin there is this separate routine to check for the error flag.

The interface is:
{{{
  SUBROUTINE PDAFomi_check_error(ierror)

    INTEGER, INTENT(in) :: ierror          ! Value of PDAF-OMI error flag
                                             ! (0): no error
                                             ! (>0): an error occured - check screen outputs
}}}

'''Notes: '''
 * The routine is provied through the module 'PDAFomi'. Thus one has to use-include the routine by 
{{{
  USE PDAFomi, only: PDAFomi_set_debug_flag
}}}
 * The errors that are checked by PDAF-OMI relate to the configuration of the obserations, e.g. it is checked whether some dimensions are consistent. 
 * If an error occurred PDAF-OMI also prints an error message, but it does not stop the program.
