Notes
=====

All times are LWA-1 local time (MT), as kept by the PC doing the collection.

All data recorded using the ARX narrowband (30-55 MHz or so) filter configuration.  
See log notes for details on which ARX channels, which stands, etc.

(A) = Duration of each contiguous/coherent acquisition.  This is the "time on the sky" represented by each file.
 
(B) = Time gap between files, denoted as follows:
  (1) Nearly contiguous.  
      Next file starts as soon as the previous one ends, 
      but probably a very brief gap (<<1s) due OS delays, etc.
  (2) Start times separated by 15 minutes

(C) = Duration of experiment; i.e., time from start of first file to start of last file.

"dataset" = name of directory containing data files.  Typically these are suffixed by "_k1" and "_k2" to indicate which PC (thus, S60 tuning) they correspond to.

"k1 Ch" and "k2 Ch" indicate the tuning of the S60 being captured by the indicated PC.  Translate as follows: 
 0:  CenterFreq=01.75~MHz, 1dB~range:  0.00- 3.50 MHz 
 1:  CenterFreq=05.25~MHz, 1dB~range:  3.50- 7.00 MHz 
 2:  CenterFreq=08.75~MHz, 1dB~range:  7.50-10.50 MHz
 3:  CenterFreq=12.25~MHz, 1dB~range: 10.50-14.00 MHz   (13.36-13.41 is RA band)
 4:  CenterFreq=15.75~MHz, 1dB~range: 14.00-17.50 MHz
 5:  CenterFreq=19.25~MHz, 1dB~range: 17.50-21.00 MHz
 6:  CenterFreq=22.75~MHz, 1dB~range: 21.00-24.50 MHz
 7:  CenterFreq=26.25~MHz, 1dB~range: 24.50-28.00 MHz   (25.55-25.67 is RA band)
 8:  CenterFreq=29.75~MHz, 1dB~range: 28.00-31.50 MHz * 
 9:  CenterFreq=33.25~MHz, 1dB~range: 31.50-35.00 MHz *
10:  CenterFreq=36.75~MHz, 1dB~range: 35.00-38.50 MHz * (37.50-38.25 is RA band)
11:  CenterFreq=40.25~MHz, 1dB~range: 38.50-42.00 MHz *
12:  CenterFreq=43.75~MHz, 1dB~range: 42.00-45.50 MHz *
13:  CenterFreq=47.25~MHz, 1dB~range: 45.50-49.00 MHz *
14:  CenterFreq=50.75~MHz, 1dB~range: 49.00-52.50 MHz *
15:  CenterFreq=54.25~MHz, 1dB~range: 52.50-56.00 MHz *

"k1-k2 time offset" indicates the time offset between k1 and k2 at the start of the observation, and my best estimate of the rate of change of this offset.

(a) Time not recorded.  I believe it was about noon.  Certainly during daylight hours.  Also, note S60 channel might have been 11, but it is probably 10 as indicated.
