Index File Information
This file contains a description of the index files created for the
Quicklook tables and from the P/Giacobini-Zinner printed archive. The
Quicklook tables are in this directory, while the printed archive tables are
in the PRNTARCH subdirectory below this one. There is also a list of
contributing observatories for P/Giacobini-Zinner data.
There are fourteen files in this directory (besides this file). The first
five (OBSCODES.DBF, OBSCODES.IDX, OBSCODES.HDR, OBSCODES.LBL and OBSCODES.STR)
are the database, index and structure files of IHW codes for the contributing
observatories. Two (QWIKPRE.IDX and QWIKPOST.IDX) are delimited tables
containing the values, in chronological order, of the IHW mandatory keywords
for all disciplines. The tables contain information from pre-perihelion and
post-perihelion respectively. Two (QWIKPRE.DBF and QWIKPOST.DBF) are dBASE
III+ compatible database files, containing no records. Similarly, *.HDR and
*.LBL are associated FITS header and PDS label files, respectively. The last
file (QWIK.STR) is a structure file describing the fields present in the .IDX
files. See the following description of the printed archive tables for more
complete details.
The PRNTARCH subdirectory contains all of the printed archive index
tables. Some disciplines have more than one kind of table in the printed
archive, corresponding to the different subnetworks. Each of the distinct
types of table included in the printed archive have been translated into a
machine readable index file in this directory.
There are six types of files in the PRNTARCH subdirectory, distinguished
by the extensions on the file names. The filenames themselves identify the
discipline and subnet which was used to produce each index. The types of files
are:
*.HDR - These are complete FITS headers for the data tables. A
fully-qualified FITS table may be created from the data table
by appending the .IDX file to the associated .HDR file, then
adjusting the length of the resulting file with the program
FITSXTND.
*.LBL - These are PDS labels describing the data tables. They already
contain pointers to the data tables, so no further steps are
required to make them accessible to PDS table-processing
software.
*.DBF - These are dBASE III+ compatible database files. They do not
contain any data records, only the structure of the
corresponding database. The data records may be appended from
the data tables (in the .IDX files). Many database management
systems can import databases from .DBF files.
*.IDX - These files contain the actual data records from each table.
They are delimited tables. Numeric fields are delimited by
commas (,) and ASCII text fields are contained in quotes (")
and also delimited with commas. Each line ends with the
characters <CR><LF> (ASCII 13 and 10 respectively). All fields
in the tables are fixed width to facilitate their use in that
format, as well. These files may be appended to the end of an
empty database structure to create the full index database.
*.STR - These are "structure" files. They contain information, in
delimited format, on the number, names and widths of the
fields in each database. They can used by dBASE III for
creating the printed archive index tables, and also document
the structure of each table.
There is one additional file (STRUCT.DBF) in this subdirectory. This is
the database used to create all the other databases. It consists of 4 fields,
FIELD_NAME, FIELD_TYPE, FIELD_LEN and FIELD_DEC, which document the structure
of the index tables. When the appropriate .STR file is appended to this
structure database, dBASE III+ can create the corresponding printed archive
index database.
