Bad Lags

The Bad Lags plot shows a time sample based autocorrelation function (ACF) RMS for each channel, board and chassis (i.e., lag consistency). When the RMS is above a clip level (shown as max in the plot), this lag channel will be flagged. Boards are color coded by their board number (notice band order is 0,2,1,3,5,4)

Bad lags

Waterfall Plot

The Waterfall Plot is a spectrum for each band, chassis and time sample, color coded by their band. We keep two versions: the original one with minimal flagging and one that has the latest flags applied after the pipeline has been re-run. This plot is produced by rsr_driver (Author: D. Sanchez)

Spectrum from rsr_sum: (Author: M.Yun)

The rsr_sum version of the average spectrum has optional blanking and sections to avoid for baseline fitting. Below are the spectra from rsr_sum (orange) and rsr_driver (blue). If there is a significant difference between the two, then there is some subtle difference in how the scripts work.

    Notes on the Redshift Search Receiver (RSR)
    1. 4 chassis represent the two beams and two polarizations; they are normally averaged to increase S/N
    2. 6 boards, which if taken in the order 0,2,1,3,5,4 are the bands sorted by increasing frequency (color coded in our plots)
    3. each board has 256 channels. For a lag space plot, see lags.png, the waterfall plot is in rsr.wf.pdf
    4. a small number of typically 30sec integrations are in each obsnum
    5. often multiple obsnums need to be stacked for a full observation. this can cover several days
    6. the final spectrum is a single band merged spectrum covering the full 73-111 GHz range, averaged in time and chassis
    7. Band edges are at 73.0, 79.7, 86.0, 92.1, 98.6, 104.9, 111.0 GHz, with a small overlap between bands.
    8. Board ranges: {0: [(71.72, 79.69)], 1: [(85.41, 93.38)], 2: [(78.02, 85.99)], 3: [(90.62, 98.58)], 4: [(104.31, 112.28)], 5: [(96.92, 104.88)]}
    9. Channel width is 31.25 MHz or about 100 km/s in the 3mm (W) band
    10. There is no source doppler tracking, though observations are on a common (helio?)centric frame
