<h1>Growth-Curve Photometry</h1>
<p class="abstract">
Growth-curve photometry is primary intended
for the absolute photometry calibration.
This routine constructs a mean radial growth-curve by using of
machine selected bright stars. Total absolute fluxes of all stars
are determined from the growth-curve.
As a side effect, the method produces less scattered
data for well radially defined images of stars. <em>Unfinished!</em>

<h2>Description</h2>
<p>
Growth-curve photometry determines absolute fluxes
of all star-like objects of frames.
sum of counts from a star in predefined apertures.

additional extensions GROWFUNC and GROWDATA are added to processed
files and create a report file (replaces .fits with .png)
with plotted details about growth curve photometry.
