Create an object for the recipe fors_img_science.
import cpl
fors_img_science = cpl.Recipe("fors_img_science")
Systematic error in magnitude (float; default: 0.01) [default=0.01].
SExtractor executable (str; default: ‘/usr/bin/sex’) [default=”/usr/bin/sex”].
SExtractor configuration file (str; default: ‘/usr/share/cpl- plugins/fors-5.0.11/config/fors.sex’) [default=”/usr/share/cpl-plugins/fors-5.0.11/config/fors.sex”].
SExtractor magnitude (str; default: ‘MAG_APER’) [default=”MAG_APER”].
SExtractor magnitude error (str; default: ‘MAGERR_APER’) [default=”MAGERR_APER”].
Background error map median filter radius (unbinned pixels) (long; default: 64) [default=64].
The following code snippet shows the default settings for the available parameters.
import cpl
fors_img_science = cpl.Recipe("fors_img_science")
fors_img_science.param.magsyserr = 0.01
fors_img_science.param.sex_exe = "/usr/bin/sex"
fors_img_science.param.sex_config = "/usr/share/cpl-plugins/fors-5.0.11/config/fors.sex"
fors_img_science.param.sex_mag = "MAG_APER"
fors_img_science.param.sex_magerr = "MAGERR_APER"
fors_img_science.param.sex_radius = 64
You may also set or overwrite some or all parameters by the recipe parameter param, as shown in the following example:
import cpl
fors_img_science = cpl.Recipe("fors_img_science")
[...]
res = fors_img_science( ..., param = {"magsyserr":0.01, "sex_exe":"/usr/bin/sex"})
