A calibrated light frame can now be generated using the master Light, Flat, Dark and Bias frames from the previous chapters. 

Step

Description

Action

1

Open the Image Calibration module

2

Add Light Frames

Use the original, unprocessed approved light frames for calibration from folder "1_Approved"

3

Output Files

use subfolder "2_CalibratedLightFrames" as storage for the calibrated light frames

4

Include the Master Bias frame

  • Uncheck Calibrate

5

Include Master Dark frame

  • check Calibrate
  • check Optimize

6

Include the Master Flat file

from previous step

IMPORTANT: Flat Frames should also include the correct filter name in the FITS header. As color light frames from an ASIAIR OSC camera never contain any filter information, they will be treated as NoFilter files and therefore the Flat Frames must have the FITS entry FILTER = NoFilter as well in order to be accepted by the WBPP or FBPP batch pre-processing scripts (see chapter Calibration Frames for more details)

7

Run the Calibration Process


Click on the (Apply Global) or hit F6


The calibrated light frames will be stored to subfolder:
"2_CalibratedLightFrames"

8

Go to next step: Debayering
