Usage example

In a shell:

                 --ncpus 16 \\
                 --no-use_numba \\
                 --no-use_gpu \\
                 --use_pyfftw \\
                 --to_disk \\
                 --verbose \\
                 --target_id "<LOFAR TARGET OBS ID>" \\
                 --reference_ids "LOFAR REFERENCE OBS ID(S)" \\
                 --input_dir "</PATH/TO/INPUT_DATA>" \\
                 --output_dir "</PATH/TO/OUTPUT_DATA>" >> ../<LOG FILE NAME>.out 2>&1
