=====Usage:=====

<code>otrack1(<var>a</var>, <var>df</var>, <var>f1</var>, <var>o</var>, <var>ob</var>, <var>amin</var>)</code>

=====Function:=====

Extract order (band) amplitudes from an amplitude spectrum.

=====Parameters:=====

;<var>a</var>

:An amplitude or power spectrum.

;<var>df</var>

:The frequency resolution of <var>a</var>.

;<var>f1</var>

:The first order frequency.

;<var>o</var>

:The order value or values (number or vector).

;<var>ob</var>

:The order tracking bandwidth.

;<var>amin</var>

:The default amplitude for unassigned order lines.

=====Result:=====

Order amplitudes of the same type as <var>o</var>.

=====Notes:=====

The order amplitude oa[i] is set to the maximum amplitude of the frequency band:<var>f1</var><code>*(</code><var>o</var><code>[i]-</code><var>ob</var><code>/2) ..</code> <var>f1</var><code>*(</code><var>o</var><code>[i]+</code><var>ob</var><code>/2)</code>
