vmimcalphot - Determine photometric calibration from a set of observed standard stars.


esorex vmimcalphot [OPTIONS] FILE.sof


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.

For more details, please refer to the VIMOS Pipeline User´s Guide.


--Extinction <bool>
Compute also extinction coefficient (bool; default: False). The full name of this option for the EsoRex configuration file is vimos.Parameters.extinction [default = False].
--ColorTerm <bool>
Compute also color term (bool; default: False). The full name of this option for the EsoRex configuration file is vimos.Parameters.colorterm [default = False].
--UseColorTerm <bool>
Use color term in zeropoint computation (bool; default: False). The full name of this option for the EsoRex configuration file is vimos.Parameters.usecolorterm [default = False].

Note that it is possible to create a configuration file containing these options, along with suitable default values. Please refer to the details provided by the 'esorex --help' command.

Basic documentation about the EsoRex program can be found at the esorex (1) man page.

It is possible to call the pipelines from python using the python-cpl package. See for further information.
