How to read Public_NoiseEvents_NASL_MX?
- This file contains all Noise Events identified at NASL during a monitoring
  period. 
- The bottom of each page indicates the Site ID.
- The columns contain the following information:
    - EventID: Unique identifier for each noise event. Used to identify which 
      noise events are associated with a flight operation.
    - StartTime: The start time (local) of the noise event
    - StopTime: The stop time (local) of the noise event
    - DurationInSeconds: The duration of the noise events in seconds
    - LAeq_SEL: The SEL for the A-weighted sound level 
    - LAeq_Leq: The Leq for the A-weighted sound level
    - LAeq_Lmax: The maximum A-weighted sound level
    - LAeq_LmaxTime: The time stamp (local) of the maximum A-weighted sound 
      level.
      
How to read Public_Operations_AircraftNoiseEvent_NASL_MX?
- This file contains all the flight operations observed at NASL Reeves Field 
  during a monitoring period. 
- The bottom of each page indicates the SiteID. The first few pages contain the 
  basic Operation information. After the basic operation information you'll find
  the info for each site.
- The info for each site is set up so that you can see which noise events were 
  associated with the flight operation. The noise events are site specific and 
  come from the Public_NoiseEvents_NASL_MX files.
- The columns contain the following information:
    - OperationID: Unique ident for each flight operation. Used to identify 
      which operation, and is consistent across sites
    - Runway: Runway at airfield for arrival/departure
    - Aircraft
    - SubType: sub-type of the operation
    - Type: type of operations (arrival/departure)
    - Fix: Waypoint used to distinguish direction the aircraft is traveling 
      towards or from
    - Distance: Qualifier to distinguish which flight track used
    - LogTime: Time stamp that indicates when the aircraft crossed the runway 
      threshold
    - TrackID: Unique identifier for flight track, corresponds to NMAP input
    - NumPOCA: Number of Points of Closest Approach. Usually one, but some 
      monitoring sites are two becasue of where they are in the pattern 
      (e.g. Overhead Break Arrival)
    - StartTimeEarliestEvent: Aircraft noise event start time
    - StopTimeLatestEvent: Aircraft noise event stop time
    - LAeq_SEL: The SEL for the A-weighted sound level 
    - LAeq_Lmax: The maximum A-weighted sound level
    - EventIDs: Noise event IDs associated with this operation.
