1.4.4. - Showscans
The
showscans
program is a shell script that serves as a front end for
an
awk
script called
show.awk,
which is installed in the spec auxiliary file directory.
The awk script prepares a C-PLOT command file that will be automatically
run to
make summary plots of scans from spec data files.
Twelve scan
plots are placed on each page.
The text is very small, so a high
resolution display device is recommended.
Usage is
showscans [options] [file_options] file [[file_options] file ...]
where the global
options
relate to C-PLOT commands and are:
-eb error_bars |
Error bar mode (default is 0, off). |
-ft font |
Font code (default is font 2). |
-sy symbol |
Symbol code (default is L, a line). |
-zi filter |
Graphics filter (default is psfilter). |
-w |
Wait for keyboard <return> after each page |
-x |
Shorthand for -zi "x11 -rotate" -w |
The
file_options
apply only to the next file on the command line and
are:
-f from_scan_number |
Starting scan number for the following file. |
-t to_scan_number |
Ending scan number for the following file. |
In no scan numbers are specified, all the
scans within a file will be processed.
File names that end with
.I
are ignored as they are assumed to
be
scans.4
index files, allowing you to use metacharacters
to specify filenames a little more freely.
The
awk
script
recognizes all the standard scan headings produced by the
standard spec scan macros and uses that information to select the
x-axis
label and the column for the independent variable in the data file.
The title of each of the small plots is the starting
Q
vector of the
displayed scan, taken from the
#Q line of the data files.
If the monitor counts are zero for any point in a scan, that
scan is not plotted.
The
show.awk
file can be edited to disable that feature.
