<h1>Scripting of DK 154 pipeline</h1>
<p class="abstract">
There is a description of development of a pipeline for
processing of images from DK154. The scripts can be modified
and used for general data processing.
</p>
<h2>Introduction</h2>
<p>
DK154 is the famous <a href="https://www.eso.org/public/teles-instr/lasilla/danish154/">Danish 1.54-meter</a> telescope at La Silla (Chilie).
</p>
<h2>Prerequisities</h2>
<p>
The frames are taken under common conditions:
</p>
<ul>
<li>Every frame includes IMAGETYP keyword in header with possible values:
LIGHT, BIAS, FLAT</li>
<li>The CCD is cooled below -100°C, so taking of darks has been abandoned by operators.</li>
<li>Biases are cheeply available. There is easy to get 15 - 20 biases per run. It is
supposed biases are get every night.</li>
<li>Flat-fileds are relative expensive to acquire. Ones are taken only one
per seasson (per month), certainly, at least not every night. Flat-fields
can be visually checked.</li>
<li>The rought sky position (± few arcmin) is known. The position
is pre-set in frame headers by telescopes's controlers.</li>
</ul>
