This is linux 2.6 (embedded)

It works great and prints 10 lines after the lines which contains search string in... (8 Replies)

Hi Guys,
I have an awk script that would search the input file for line that starts with a number 3 and copies into a new text file.
I want to extend this script to find the lines that either starts with 3 or a or b and copy all those lines into the new file.
Here is what I have so far:... (1 Reply)

"cross_section"
Example:
$xsec = Xray::Absorption -> cross_section($elem, $energy, $mode);
@xsec = Xray::Absorption -> cross_section($elem, @energy, $mode);
The $mode argument is different here than for the other resources. The options are "xsec", "photo", "coherent" and "incoherent",
telling this method to return the full cross-section or just the photoelectric, coherent, or incoherent portions.
The values for all cross-sections are computed as log-log polynomials as described in the original paper by McMaster et al.
NAME
Xray::Absorption::McMaster - Perl interface to the McMaster tables
SYNOPSIS
use Xray::Absorption;
Xray::Absorption -> load("mcmaster");
See the documentation for Xray::Absorption for details.
DESCRIPTION
This module is inherited by the Xray::Absorption module and provides access to the data contained in the 1969 McMaster tables.
The data in this module, commonly referred to as "The McMaster Tables", was originally published as
Compilation of X-Ray Cross Sections
W.H. McMster, N. Kerr Del Grande, J.H. Mallett, J.H. Hubbell
National Bureau of Standards
UCRL-50174 Section II Revision 1(1969)
Available from National Technical Information Services L-3
United States Department of Commerce
This can be a bit difficult to find. IIT's Galvin library has kindly made a scan of it available:
http://www.gl.iit.edu/govdocs/resources/xray.html
The data is contained in a database file called mcmaster.db which is generated at install time from a flat text database of the McMster
data. The data originally comes from mucal.f, a Fortran subroutine originally written by Dr. Pathikrit Bandhyapodhyay.
The required Chemistry::Elements module is available from CPAN in the miscellaneous modules section.
EDGE AND LINE ENERGIES
The McMaster data resource only includes K and L 1-3 edges. For light elements, it provides only a single L edge energy -- that for the L1
edge. For heavier elements it provides a single M energy, the energy of the M1 edge. It only supplies four generic fluorescence line
energies, Kalpha, Kbeta, Lalpha, and Lbeta. In each case the energy provided is the energy of the brightest line of that sort.
BUGS AND THINGS TO DO
o Make sure this handles fluorescence lines which are in other resources, but not in this resource in a sensible manner.
o What happens if you call "line_toggle" when this is loaded? How about when elam was loaded but then you switch to this one?
