* THIS FILE MUST BE NAMED       SEGYKEYW.ORD     
* AND THE FILE MUST BE IN THE SYSTEM'S SEARCH PATH.
*
*This file defines the valid keywords that the SEG2SEGY program understands
*any line beginning with * is ignored by keyword parser.
*general form of keyword line is:
*
*  KEYWORD  function#  parm0 [parm1 parm2 ... parm10]
*
*currently defined functions:
*
*0-keyword is acknowledged as a valid keyword, however no information
*  can be used by SEG-Y format.
*
*1-Insert an integer (16 bit) value in input-stream in header
*  location after multiplying by parm1. INTEGER VALUE ONLY (Subset
*  of function 5)
*
*2-Special function for TRACE_SORT and UNITS
*  Inspect string in data stream  and insert
*  appropriate value in seg-y reel header location.
*  See code (keysegy.c) for details
*
*3-copy the string found on this input line to the segy-reel header
*  line (1-40)identified by seg-header -value.
*  Each line is 80 chars long (80*40=3200)
*
*4-Special function like #2 trace type this time.
*
*5-Modified function 1. header location represents data type in 
*  input stream. 0=int. 1=long int, 2=floating point 3=fp stored as fp header word
*  parm 1 is multiplier. parms2-10 are the seg-y header locations (16-bit)
*  of each value on the input list. use with
*  keywords that have more than one value/line. See descriptions
*  with ALIAS_FILTER
*
*6-Special function for ACQUISITION_DATE
*  Inspect string in data stream  and insert
*  appropriate value in seg-y trace header location.
*  See code (keysegy.c) for details
*

ACQUISITION_DATE 6 79
ACQUISITION_TIME 5 0 1 81 82 83
ALIAS_FILTER 5 0 1 71 72
*the above is function 5, the 0 means int, the 1 is the multiplier
*and the values are to be inserted in locations 71 and 72 of the
*seg-y trace header. 
CDP_NUMBER 5 1 1 12
*in the above function 5 defines the input-value to be a long integer
*(first 1) to be inserted into byte location 12 after being multiplied
*by 1 (second 1)
CDP_TRACE 5 1 1 14
CHANNEL_NUMBER 5 1 1 8
DATUM 5 2 1 27 
DELAY 1 55 1000
*delay is simple integer therefore use function 1.
*seg-y wants the time in ms . SEG-2 supplies
*time in seconds, therefore the multiplier of 1000
DESCALING_FACTOR 5 3 1 119
END_OF_GROUP 1 88 1
*seg-y calls END_OF_GROUP  'last-trace-flag'
FIXED_GAIN 1 61 1
HIGH_CUT_FILTER 5 0 1 76 78
JOB_ID 3 9
LOW_CUT_FILTER 5 0 1 75 77
NOTCH_FREQUENCY 5 0 1 73 74
*notch in SEG-2 does not currently define slope.
RAW_RECORD 5 1 1 6
RECEIVER_LOCATION 5 2 1000 41 43 21
*seg-y identifies the above as Group-coordinates
RU_ADDRESS_NUMBER 5 0 1 86 87
SAMPLE_INTERVAL 1 59 1000000
*segy expects time in micro-seconds therefore multiplier = 1e6
SOURCE_LOCATION 5 2 1000 37 39 25
*segy identifies the above as source-coordinate
*SHOT_SEQUENCE_NUMBER 1 6 1
SHOT_SEQUENCE_NUMBER 5 1 1 10
