The master-dark frame is an image made of several dark images. The dark image is used in a process of CCD image calibration. To reduce a noise of a result, it is advisory to make a number of raw dark frames and combine them into one correction frame. The Master-dark tool in the Muniwin program provides a simple method how to do that.
Clear the table of source files. Click on the Files -> Clear files item in the main menu.
Add raw dark frames to a table using the Files -> Add folder item or the Files -> Add files item. See the chapter Redution of CCD frames for details. Always combine files of the same exposure duration only.
Make a copy source files. Click on the Files -> Fetch/convert files item in the main menu.
Click on the Files -> Master-dark frame item. A new dialog appears. In the dialog, specify whether all files shall be processed or only the selected ones. Confirm the dialog by the OK button. In the following dialog select a directory and enter the name of output file where a new master-dark frame shall be saved to. Press the Save button.
When a task is finished, a new preview window appers. A new master-dark frame is displayed in the window.
