The vmimcalphot recipe¶
-
vmimcalphot
¶
Synopsis¶
Determine photometric calibration from a set of observed standard stars.
Description¶
This recipe is used to determine night zeropoints, atmospheric extinction coefficients, and colour terms, from a set of star match tables produced by the recipe vmimstandard. The star match tables may refer to different standard star fields, but they must all be derived from exposures made with the same filter and the same quadrant.
Input files¶
DO category: Type: Explanation: Required:
IMG_STAR_MATCH_TABLE Product Lust of standard stars Y
PHOTOMETRIC_TABLE Calib Photometric table Y
Output files¶
DO category: Data type: Explanation:
PHOTOMETRIC_TABLE FITS table Upgraded photometric table
The only product of this recipe is an upgraded PHOTOMETRIC_TABLE, carrying the newly computed zeropoint, and, if requested, new extinction and colour coefficients.

Constructor¶
-
cpl.
Recipe
("vmimcalphot") Create an object for the recipe vmimcalphot.
import cpl
vmimcalphot = cpl.Recipe("vmimcalphot")
Parameters¶
-
vmimcalphot.param.
Extinction
¶ Compute also extinction coefficient (bool; default: False) [default=False].
-
vmimcalphot.param.
ColorTerm
¶ Compute also color term (bool; default: False) [default=False].
-
vmimcalphot.param.
UseColorTerm
¶ Use color term in zeropoint computation (bool; default: False) [default=False].
The following code snippet shows the default settings for the available parameters.
import cpl
vmimcalphot = cpl.Recipe("vmimcalphot")
vmimcalphot.param.Extinction = False
vmimcalphot.param.ColorTerm = False
vmimcalphot.param.UseColorTerm = False
You may also set or overwrite some or all parameters by the recipe parameter param, as shown in the following example:
import cpl
vmimcalphot = cpl.Recipe("vmimcalphot")
[...]
res = vmimcalphot( ..., param = {"Extinction":False, "ColorTerm":False})
