| - | A series of tests were ran on dragnet (drg01), directly (now through slurm), on fits files from a random LOTAAS observation. Number of cores,means number of different fits files processed simultaneously. The total time is an extrapolation of this benchmark. | + | A series of tests were ran on dragnet (drg01), directly (now through slurm), on fits files from a random LOTAAS observation.
