[evlatests] Frequency Labeling -- reviewed

[Rick Perley]

    I realized this morning that I had an indexing error in my 
calculations of the labelled frequencies in yesterday's 125-kHz L-band 
test. 

    When properly computed, the reported frequencies of any given RFI 
spike (independent of which sub-band) are all 62.5 kHz too high -- 
one-half of one channel.  (This based on presuming the frequencies given 
to me by Michael refer to the bottom edge of  channel 1 in sub-band 1). 

    This is the same offset (in units of channels) that is found with 
500 kHz resolution.
