Detailed description of the data product
========================================
.. DetailedDescStart

The VIS processing function provides a series of catalogues delivered in FITS “LDAC” format. These catalogues are produced using SExtractor (Bertin & Arnouts 1996).

The :ref:`VisPSFModel` is given in entry of the VIS pipeline for fitting a spread model. 
The spread model is then used to calculate a zero point by comparing to Gaia data. 

This calibrated catalogue contains 2 types of tables :

     - The LDAC_IMHEAD table, a 1-column catalogue containing the header and some information (like SE parameters) of the original image.

     - The LDAC_OBJECTS table, a 84-colum catalogue. These columns are described below.

We calculate the magnitude in 4 apertures : 7, 13, 26 and 50 pixels.

An aperture correction is calculated with the differences between magAper 13 and magAper 50.
Then the relevant aperture to use is mag_aper 13 with this aperture correction (APERCORR).

Changes introduced by the PF version
------------------------------------

PF 17.0
*******

* MAG_AUTO is now a calibrated magnitude, and the raw value is stored in the new column MAG_AUTO_RAW
* MAG_APER[0] (7-pixel aperture), MAG_APER[2] (26-pixel aperture), MAG_APER[3] (50-pixel aperture) are now calibrated magnitudes
* raw values of 7, 13, 26, 50-pixel aperture magnitudes are stored in new columns MAG_APER_RAW[0-3]
* calibrated fluxes and associated errors are stored in new columns FLUX_AUTO_CAL / FLUX_APER_CAL and FLUXERR_AUTO_CAL / FLUXERR_APER_CAL

User case
---------

**Selection of Stars:** You can use the spread model to select all the stars of the catalogue (i.e. abs(SPREAD_MODEL) :math:`< 0.003`). 
However this can also select cosmic rays that are not correctly detected. We recommend to also use a selection in magnitude and FLUX_RADIUS for better results.
If you want no saturated star, you need also to select object with Flags=0.

| **Selection of valid pixels:** To select an object with only valid pixels, you must use: 
| *IMAFLAGS_ISO != VIS_FLAG[INVALID]*
| which is equivalent to  *IMAFLAGS_ISO%2 == 0*.
