bayesImage

This tool generate a list of images catalogs in a new directory image. It computes as many catalogs as lines in the bayes.dat files.

Syntax : bayesImage [OPTION] <.par>
Available OPTIONS:
 -b : compute images of system barycenter [default]
 -i : compute counter images, image per image

Argument: The parameter file used for the optimization. Do not use the best.par or bestopt.par produced after optimization.

Options:

  • -b Uses the image catalog specified with the multfile keyword in the image section. The barycenter of each system of images is computed and its counter images are found with the grid technique.

  • -i Uses the image catalog specified with the image keyword in the runmode section. The counter images for each individual image is computed with the grid technique.

bayesImage.sh

This script located in the directory ./perl, calls the bayesImage tool, and concatenates all the multiple images catalogs in one file bayesImage.all, and display it in DS9 if opened.

Syntax : bayesImage.sh <.par>

Argument: The parameter file used for the optimization. Do not use the best.par or bestopt.par produced after optimization.

The call to bayesImage is done with option -b.

Note that only the first 5000 images are transferred to DS9. This number is set at the beginning of the script bayesImage.sh.

predT0.h

This script is in ./utils, and serves to yield a reference pivot ICM temperature, in the X-ray section, where keywords Temp0 and Jz_array are proper to the hydrostatic X-ray profiles (type 2).

Temp0 is the pivot temperature model, eq. (17) in Allingham+23b <https://arxiv.org/abs/2309.07076>_: :math:T_0(z) = T_{500,c} (z) T_{\rm ref}. It may be computed using routine predT:

.. code-block:: console

predT0 <redshift> <model_type> <M_500,c>

where the mass :math:M_{500,c} is in :math:M_{\odot}, and the <model_type> corresponds to the regression used for :math:P_e (n_e). By defult, use polyEv1 for the latter.

Jz_array indicates how to compute the Jz function, relating the potential to the ICM density :math:n_e. It takes three arguments:

  • An integer. 0: do not perform the computation. 1: perform it.

  • A string for the model type. By default, use polyE.

  • A second string for the name of the output array. If the array is not computed (0), this array must already exist.
