[evlatests] RFI Perusing

[Rick Perley]

    For those interested in perusing the spectral plots, I've made eps 
copies from the Dec 2011 and June 2012 scans.  These can be found in my 
FITS area:

    /DATA/SECHELT_1/FITS

    labelled:

    RFI-DEC11.eps 
    and
    RFI-JUN12.eps

    for the 1 GHz-wide plots.

    Zoom-in plots (individual subbands from 1 through 8 GHz, and blocks 
of four subbands for 8 through 50 GHz) are labelled:

    RFI-DEC11-HIRES.eps
    and
    RFI-JUN12-HIRES.eps

    These spectra a in logarithmic units:  log10(S) (*not* in decibel 
units), and are *uncalibrated* -- i.e. raw amplitude.  (I couldn't 
calibrate the June 2012 spectra because the SY tables were absent).  
However, for the low frequencies, the base noise level is about -0.2 on 
the yaxis (i.e., about 0.5 Jy), while for the high frequency bands it is 
about +0.2 (i.e., about 1.5 Jy). 

    We'll get these plots to the appropriate web page in the near future.
