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})
