<HEAD><TITLE>CSR -- Class Signature Reporter</TITLE></HEAD>


<H1>CSR -- Class Signature Reporter</H1>
Generates a soft-copy or hard-copy report for class signatures.

<H3>PARAMETERS</H3>
CSR is controlled by the following global parameters:
<P>
<pre>Name     Prompt                                  Count     Type
FILE     Database File Name                      1-64      Char
DSIG     Database Class Signature Segment        1         Int
REPORT   Report mode: TERM/OFF/filename          0-64      Char
</pre>
<H4>FILE</H4>
Specifies the name of the PCIDSK image file containing signatures to
be &quot;printed&quot;.
<P>
<PRE>
 EASI&gt;FILE=&quot;filespec&quot;
</PRE>
<H4>DSIG</H4>
Specifies the segment (type 121) number of an EXISTING class
signature segment on which to report.
<P>
<PRE>
 EASI&gt;DSIG=i
</PRE>
<H4>REPORT</H4>
Specifies the file to which the generated report should be appended.
<P>
<PRE>
 EASI&gt;REPORT=&quot;filename&quot;
 EASI&gt;REPORT=            | defaults to terminal output
</PRE>
The following names have special meaning:
<P>
<PRE>
 EASI&gt;REPORT=&quot;TERM&quot;      | generates reports on your terminal
 EASI&gt;REPORT=&quot;DISK&quot;      | generates reports on file &quot;IMPRPT.LST&quot;
 EASI&gt;REPORT=&quot;OFF&quot;       | switch off report generation
</PRE>
<H3>DETAILS</H3>
CSR provides a report of the statistical values as calculated by CSG
for a specified signature segment (DSIG). These include the
following:
<P>
<UL>
<LI> CORRELATION MATRIX for all selected channels; 
<LI> COVARIANCE MATRIX, DETERMINANT OF COVARIANCE MATRIX, INVERSE
COVARIANCE MATRIX, and TRIANGULAR INVERSE COVARIANCE MATRIX for
all selected channels; 
<LI> MEAN and STANDARD DEVIATION for each selected channel; 
<LI> Classification grey-level coding VALU for the classified output
Theme Map; 
<LI> Gaussian THRESHOLD value (in standard deviation units) for radius
of hyperellipsoid from class mean; 
<LI> LOWER and UPPER distances (in standard deviation units) of
parallelepiped boundaries from channel means; 
<LI> Relative 'a priori' probability weighting (BIAS). 
</UL>
This report will be forced to your terminal if reporting has been
disabled by the user.<p>
NO modifications to the segment (type 121) are provided.<p>
(Try HELP CSG DETAILS and HELP CSE DETAILS for more information.)

<H3>EXAMPLE</H3>
This example reports on signature 13 of the file SPOT512.
<P>
<PRE>
 EASI&gt;FILE=&quot;SPOT512&quot;            | specify file
 EASI&gt;DSIG=13                   | input signature
