skarabina: a basic 1GC radio astronomy RFI flagger

Author: Tim Molteno (tim@elec.ac.nz)

Intended to reduce I/O costs by performing the standard flagging during 1GC efficiently, and with low memory requirements. Skarabina can also do averaging to reduce data volume, and measurement set analysis to recommend image size.
