x2sys_put - Update x2sys track data bases
SYNOPSIS
x2sys_put [ info.tbf ] -TTAG [ -D ] [ -F ] [ -V ]
DESCRIPTION
x2sys_put accepts a track bin-index file created by x2sys_binlist and adds this information about the data tracks to the relevant data
base. You may chose to overwrite existing data with new information for older tracks (-F) and even completely remove information for cer-
tain tracks (-D). The x2sys TAG must match the tag encoded in the info.tbf file. To inquire about tracks in the data base, use x2sys_get.
-T Specify the x2sys TAG which tracks the attributes of this data type.
OPTIONS
No space between the option flag and the associated arguments.
info.tbf
Name of a single track bin file. If not given, stdin will be read.
-D Delete all tracks found in the track bin file [Default will try to add them as new track entries].
-F Replace any existing database information for these tracks with the new information in the track bin file [Default refuses to
process tracks already in the database].
-V Selects verbose mode, which will send progress reports to stderr [Default runs "silently"].
EXAMPLES
To add the information stored in the track bin-index file latest.tbf to the track data bases associated with the tag MGD77, and replace any
exiting information for these tracks, try
x2sys_put latest.tbf -F -V -TMGD77
X2SYS DATABASES
The x2sys_put utility adds new information to the x2sys data bases. These consists of two files: The first file contains a listing of all
the tracks that have been added to the system; it is named TAG_tracks.d and is in ASCII format. The second file is named TAG_index.b and
is in native binary format. It contains information on which tracks cross each of the bins, and what data sets were observed while cross-
ing the bin. The bins are defined by the -R and -I options passed to x2sys_init when the TAG was first initiated. Both data base files
are stored in the $X2SYS_HOME/TAG directory. Do not attempt to edit these files by hand.

x2sys_report - Report statistics from crossover data base
SYNOPSIS
x2sys_report -Ccolumn -TTAG [ coedbase.txt ] [ -A ] [ -I[list] ] [ -L[corrtable] ] [ -Nnx_min ] [ -Qe|i ] [ -Rwest/east/south/north[r] ] [
-Strack ] [ -V ]
DESCRIPTION
x2sys_report will read the input crossover ASCII data base coedbase.txt (or stdin) and report on the statistics of crossovers (n, mean,
stdev, rms, weight) for each track. Options are available to let you exclude tracks and limit the output.
-C Specify which data column you want to process. Crossovers related to this column name must be present in the crossover data base.
-T Specify the x2sys TAG which tracks the attributes of this data type.
OPTIONS
No space between the option flag and the associated arguments.
coedbase.txt
The name of the input ASCII crossover error data base as produced by x2sys_cross. If not given we read standard input instead.
-A Eliminate COEs by distributing the COE between the two tracks in proportion to track weight and producing (dist, adjustment) spline
knots files for each track (for the selected column). Such adjustments may be used by x2sys_datalist. The adjustment files are
called track.column.adj and are placed in the $X2SYS_HOME/TAG directory. For background information on how these adjustments are
designed, see Mittal [1984].
-I Name of ASCII file with a list of track names (one per record) that should be excluded from consideration [Default includes all
tracks].
-L Apply optimal corrections to the chosen observable. Append the correction table to use [Default uses the correction table TAG_cor-
rections.txt which is expected to reside in the $X2SYS_HOME/TAG directory]. For the format of this file, see x2sys_solve.
-N Only report data from tracks involved in at least nx_min crossovers [all tracks].
-Q Append e for external crossovers or i for internal crossovers only [Default is external].
-R west, east, south, and north specify the Region of interest, and you may specify them in decimal degrees or in
[+-]dd:mm[:ss.xxx][W|E|S|N] format. Append r if lower left and upper right map coordinates are given instead of w/e/s/n. The two
shorthands -Rg and -Rd stand for global domain (0/360 and -180/+180 in longitude respectively, with -90/+90 in latitude). Alterna-
tively, specify the name of an existing grid file and the -R settings (and grid spacing, if applicable) are copied from the grid.
For Cartesian data just give xmin/xmax/ymin/ymax. This option bases the statistics on those COE that fall inside the specified
domain.
-S Name of a single track. If given we restrict output to those crossovers involving this track [Default output is crossovers involv-
ing any track pair].
-V Selects verbose mode, which will send progress reports to stderr [Default runs "silently"].
EXAMPLES
To report statistics of all the external magnetic crossovers associated with the tag MGD77 from the file COE_data.txt, restricted to occupy
a certain region in the south Pacific, try
x2sys_report COE_data.txt -V -TMGD77 -R180/240/-60/-30 -Cmag > mag_report.txt
To report on the faa crossovers globally that involves track 12345678, try
x2sys_report COE_data.txt -V -TMGD77 -Cfaa -S12345678 > faa_report.txt
