Adding extra static RFI flagging based on time stamps #45

Closed hgan0 closed 1 year ago

hgan0 commented 1 year ago

As discussed in the power spectrum workshop, the following bands are added to the RFI flagging routine:

(1) 505.85 - 511.71 MHz: 6 MHz band (reported by Simon) applied to all CSDs (2) 584.00 - 590.00 MHz & 596.00 - 602.00 MHz: UHF TV channels 33 & 35 (reported by Seth) applied from CSD 2983 (3) 617.00 - 627.00 MHz: Rogers’ new 600 MHz band (reported by Seth) applied from CSD 2243 (4) 716.00 - 728.00 MHz: Blobs, channels 55 & 56 applied from CSD 2080

Each flagging band in bad_frequencies now has a corresponding time stamp (start observing time in UNIX time). frequency_mask has an extra timestamp input to compare with the start observing time of each flagging band. static_rfi_mask_hook in ch_pipeline/analysis/flagging.py needs an extra timestamp input.
