Description Of The Tape.

     Data from the tests performed for the contract are entered
in a single file on magnetic tape.
the parameters  for processing the tape.

      The  tape  was delivered to
            Mr. Paul Truchan
            U.S.  Environmental Protection Agency
            Air Program Branch

            New York, N.Y. 10278
 Types  Of Records In The  File.

     Each record in the  files  is an 80 column card image and is
•one of the following types:

       Type 1.  Header
            2.  Test Result
            3.  Atmospheric Data
            4.  Keymode Test Results - I
            5.  Keymode Test Results - II
            6.  Tune Up Data - I
            7.  Tune Up Data - II
            8.  Comment Continuation
            9.  Warning Record

      The formats of the nine types are shown in Tables B thru J.


 Record Sets.

      Records are grouped into sets, each set containing the results
 from a series of tests performed on a vehicle.

-------
                            -2-
     Individual  sets  are  identified by a unique  four digit test
series number  entered in  column  74 thru 78 of each record in the
set.  Test  series  numbers were assigned in chronological order.
The records in a set  are  numbered consecutive starting with 001.
The record  number  is  entered  in  column' 78 thru 80.

     Sets belonging to the Inspection/Maintenance  (I/M) study
appear first in  the file  followed by  sets from the Retrofit study.
The I/M sets appear in pairs  consisting of a "before tune up"
followed by an "after tune up" set for the same  vehicle.  The
pairs are ordered  according to the ascending sequence of "before
tune up" test  series  numbers.   (Note  there are no  "after tune up"
sets to match  the  "before tune up" set 2367 and  2798). The Retrofit
set are arranged in ascending order by vehicle identification
number (on  the Header record) and test series number. Some sets
are part of both the  I/M  and  Retrofit studies.   The   test series
number is the  same for both occurances of the set.
Description Of The  Sets.

     The first record  in  every set is a Type 1 Header record.
I/M sets are identified by a  "1" in column 5.  Retrofit sets have
a blank in column 5.   A typical set contains one or  two Type 2
records giving the  results of N.Y. Quick tests and one or two
Type 2 records giving  the results of C39 or C39H tests.  Each
Type 2 record is followed by  a Type 3 record giving  the ambient
atmospheric data taken during the test.

     The set contain results  of a Keymode test.  There is some
variability in the  way Keymode tests were coded.  At the beginning
of the study they were coded  on a single Type 4 record.  However,
during the study it was decided to make additional kinds of mea-
surements .  The Type 4 record could not accommodate  the additional
readings and the Type  5 record was created to hold them. Also
during the study a  second analyzer system became available and it
was decided to record  measurements from both systems.  Thus as
many as four records are  required to hold the Keymode results, a
Type 4 record and a Type  5 record for each analyzer.  The set may
contain tune up data.  These  data are recorded on a  Type 6 and a
Type 7 record.  For I/M sets  the tune up records are included in
the "before tune up" sets.

     Comments may be included in Type 1,2,5 and 7 records.  If a
comment is too long to fit it is continued on one or more Type 8
records.  Comments  for Type 4 records are entirely contained on
Type 8 records.  As a  convenience for programming the I/M print-
outs that are contained in Appendix III, Type 9 records were
inserted at the end of I/M sets containing fewer than two C39 or
C39H test records.

      is entered if there is no comments, a "1" is entered if the comment
      is entirely contained on the record, a "2" is entered if the comment
      is continued on a single Type 8 record, etc.  However, becuase of
      an inconsistancy in coding,  a zero instead of a "1" is coded on
      Header records for a comment entirely contained on the record.

     The values in column 42 and 43 are given only on the first Test
Result record in the set.  In the subsequent Test Result records of
the set these columns are blank.

     Carbon dioxide is not of interest in the study and is not included
in the contract.  However, carbon dioxide measurements were taken and
coded.  The carbon dioxide results on Retrofit Test Result records were
edited for keypunch errors.  The results on I/M records were not edited
and may contain keypunch errors.

    The units for hydrocarbon and oxides of nitrogen reading are ppm.
arbon monoxide readings are in percent.  However, in a very few of the
arliest Keymode test the carbon monoxide reading are coded in ppm. If the
arbon monoxide reading is in percent a "1" is coded in the column preceeding
he reading, if the carbon monoxide reading is in ppm a blank or a zero is
oded in the perceeding column.

    As explained in the text some Keymode test results are coded on a
ingle record while others are coded on four records.  When four records
re present a "1" is coded in column 70 of the first Keymode record.  If
     is only a single Keymode record the column is left blank.
