Description
We present 𝚝𝚊𝚋𝚊𝚜𝚌𝚊𝚕, (𝐓r𝐀jectory 𝐁𝐀sed RFI 𝐒ubtraction and 𝐂𝐀𝐋ibration), a new algorithm that jointly models the RFI signal, trajectory, antenna gains, and residual visibilities to recover RFI-free interferometry data. We show that 𝚝𝚊𝚋𝚊𝚜𝚌𝚊𝚕 improves image quality beyond what is achieved with the standard flagging approach as well as existing RFI subtraction techniques. 𝚝𝚊𝚋𝚊𝚜𝚌𝚊𝚕 has been further improved to overcome scalability and generalisation issues that had previously held it back.
