Scripting of DK 154 pipeline
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.
Introduction
DK154 is the famous Danish 1.54-meter telescope at La Silla (Chilie).
Prerequisities
The frames are taken under common conditions:
- Every frame includes IMAGETYP keyword in header with possible values:
LIGHT, BIAS, FLAT
- The CCD is cooled below -100°C, so taking of darks has been abandoned by operators.
- Biases are cheeply available. There is easy to get 15 - 20 biases per run. It is
supposed biases are get every night.
- 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.
- The rought sky position (± few arcmin) is known. The position
is pre-set in frame headers by telescopes's controlers.
