Ubuntu Manpage: x2sys_report - Report statistics from crossover data base

NAME

       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_corrections.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). Alternatively, 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 involving 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 -T MGD77 -R 180/240/-60/-30 -C mag > mag_report.txt

       To report on the faa crossovers globally that involves track 12345678, try

       x2sys_report COE_data.txt -V -T MGD77 -C faa -S 12345678  > faa_report.txt
