The hawki_detector_noise recipe¶
- hawki_detector_noise¶
Synopsis¶
HAWKI detector noise recipe
Description¶
hawki_detector_noise – HAWKI recipe to find readnoise and gain.
Compute the readnoise and gain for the hawki detectors using two dark frames and two flat field frames. Both must have been exposed with NDIT=1 The program accepts the following files in the SOF:
Tag Description DARK A list of raw dark images FLAT_TWILIGHT A list of raw flat images MASTER_BPM Optional master bad pixel mask or MASTER_CONF Optional master confidence map
If a master bad pixel mask or confidence map is included then thebad pixels will be flagged during the statistical analysis
Constructor¶
- cpl.Recipe("hawki_detector_noise")
Create an object for the recipe hawki_detector_noise.
import cpl
hawki_detector_noise = cpl.Recipe("hawki_detector_noise")
Parameters¶
- hawki_detector_noise.param.thresh¶
Rejection threshold in sigma above background (float; default: 5.0) [default=5.0].
The following code snippet shows the default settings for the available parameters.
import cpl
hawki_detector_noise = cpl.Recipe("hawki_detector_noise")
hawki_detector_noise.param.thresh = 5.0
You may also set or overwrite some or all parameters by the recipe parameter param, as shown in the following example:
import cpl
hawki_detector_noise = cpl.Recipe("hawki_detector_noise")
[...]
res = hawki_detector_noise( ..., param = {"thresh":5.0})
See also
cpl.Recipe for more information about the recipe object.
