| 37 | This should allow us to very effectively excise this RFI with an automated routine. |

| 39 | One option is to use Pieflag, Enno Middleberg's automatic flagging script. It works by looking at each channel in turn |
| 40 | through time, and finding outliers in comparison to a channel that is known not to have RFI. This works quite well for |
| 41 | continuum datasets from the old correlator, since there are fewer channels. Pieflag loads the |
| 42 | entire dataset into memory, which can be quite a strain on a computer that does not have enough memory for the datasets |
| 43 | that CABB will produce. |

| 45 | Another option is to use a script made by Jamie Stevens to look for narrowband RFI (which is attached to this page). |
| 46 | This script looks for individual channels that deviate from the median by more than an acceptable amount. |
