The observation modification commands (reject/ignore/reweight)_observation and set_observation_options can silently fail to be applied if they include data_file=xxx criteria and the data files have not already been specified in data_file commands.
This is misleading, particularly if wildcards are used in the filenames. SNAP should work equally well if these commands are after placed before the corresponding observation commands.
