FILE AND DATABASE LOCATIONS
			
RAW DATA:   The raw data is simply a copy of the two USB sticks for each station.
             This is stored on a network storage device (NAS) called seismonas
             The copies of each USB stick are in:
              /net/seismonas/volume1/seismonas/RAW-SEISMIC-DATA/Johnson-Shut-Ins/serv-X
              where X is the service number (1,2 or3).
              Inside the service directory there is a directory for the station: JSP1, JSP2 and JSP3
              Inside the station directory is a USB stick directory with the convention that 
              disk1 is a copy of the USB with data on it - i.e. the first USB written to.
              
              The raw data for station JSP2 from the first service is then 
              /net/seismonas/volume1/seismonas/RAW-SEISMIC-DATA/Johnson-Shut-Ins/serv-1/JSP2/disk1
              
This is used only one time to make miniseed day volumes which are stored on "mantle"

DAY VOLUMES:
	      The miniseed day files are stored on "mantle" in
	           /RAID/DB/Johnson-Shut-Ins/data_files/serv-X
	           where X is the service number.

NOTE a few things: 
   i) The Q330S programs produced miniseed files with a "loc" code of "00"
      I changed the names of all day files and changed the miniseed headers to reflect
      that the "loc" code is "null"
      
   ii) The Q330S programs produced channels EL1, EL2,  LL1 and LL2
       rename all horizontal data file channels to be; ELN   ELE     LLN  LLE
       use  programs/re-name-1-2-chan.pl            
       AND changed the miniseed headers to reflect this.
       
  iii) "fixhdr" which is what we use to fix or modify the miniseed headers does NOT work on "mantle".
  
  
  
  
DATABASES:
    There are two databases in /RAID/DB/Johnson-Shut-Ins      JSPdb   and JSPALLdb
        JSPdb contains ELx and LLx data only
        JSPALLdb contains the data files ELx and LLXx as well as all the log files
        
        You can use "dbpick" on either.
        I use "dbpick" displaying only the LLx files for a quick look at the data
        
SAC FILES:   There is a directory called sac which contains the data in sac format
        The file nameing convention is:
             YYYYDDDHHMMSS.ds.{station}.{channel}

                 file names are:    {station name}.{net code}..{channel}.{year}.{julian day}
                           channel EHN  EHE   EHZ    -  200 sps data
                                   LHN  LHE   LHZ    -    1 sps 
                                   
databases:    /RAID/DB/Johnson-Shut-Ins/JSPdb -> data only  EH* and LH*
              /RAID/DB/Johnson-Shut-Ins/JSP-ALLdb -> all data and log files
              
              dbpick JSPdb -> quick way to scan all the data
              pql {data file names}  -> can look at data and look at frequency components
              
SAC files ->  /RAID/DB/Johnson-Shut-Ins/sac -> all files
              file names are:  YYYYDDDHHMMSS.ds.{station}.{channel}
                   YYYY: year (2022)
                   DDD : julian day
                   HHMMSS.ds :  hour minute second and decimal second of the start of the trace.
              You can write SAC macros for most of the tasks you might need.
