SR-4 WE have created an internal RFI mask for the RTA3, the channels which are corrupted are shown in the new files in the conf directory. Each band has a separate RFI mask for nternal RFI. Also updated the monitor_conf to contain a method to remove internal RFI from spectra. At the moment this is done by removing the channel with the RFI and linearly interpolating missing data. Currently only the current spectrum (as collected from current_spectra.py) has internal RFI removed, but the method in monitor_conf can be applied to any spectrum. The rfi_monitor class was updated so that the band of operation can now be changed while the rfi_monitor is running. The current mode is stored in shared memory, this shared memory location can be edited using the method rfDB2.rfi_monitor.change_mode. The rfi_monitor checks to see that this value has changed and reprograms the RTA when it sees a change. This way we can alter the band of operation by running that method in a python shell. The rta3web code (https://github.com/ska-sa/rta3web) will check the current capture mode using this same shared memory to ensure that the correct frequencies are displayed in the web visulisation.
