Set of analysis tools of MRS data

Project description

Documentation Status

AstroCabTools

Set of tools made in order to:

  • Integrate processing tools, algorithms, visualization and data analysis of images and 3D infrarred spectroscopy for the James Webb Espacial Telescope (JWST).
  • Integration of JWST calibrated data and advance products into astronomics data bases and astrophisics specialized packages.
  • Develop procedures to the JWST data combination and the joint analysis of large volumnes of data.
  • Simulation and study of observationes made from the MIRI tool of the JWST with the MIRISim simulator.

Tools

  • mrs_chan.py - To identify wich channels from the MRS range, an emitted wavelenth is (BETA version).
  • mrs_spec_chan.py - Visualization of relationship emitted wavelength and density flux associate (BETA version).
  • mrs_det_plot.py - Manipulation of astronomic images based of frame and integration values (BETA version).
  • fit_line.py - Representation of multiple gauss fitted models based on an spectrum.
  • cube_ans.py - Representation and analyisis of miri cubes
  • all_tools - Interface that allows to load each tool without using command line.

Packages used

For each tool, this repo uses a number of libraries and packages on python:

  • PyQt - Binding of C++ GUI library
  • Numpy - Library that allow large data manipulation
  • Matplotlib - Graph visualization library.
  • Astropy - Collection of software packages used for astronomy
  • Seaborn - Statistical data visualization
  • Lmfit - Non-Linear Least-Squares Minimization and Curve-Fitting for Python
  • PyPuSub - A Python publish-subcribe library
  • Photutils - Package that provides tools for detecting and performing photometry of astronomical sources.

Tested with

  • Python (tested for 3.7.0)
  • Matplotlib (tested for 3.1.2)
  • Numpy (tested for 1.81.1)
  • PyQt5 (tested for 5.14.0)
  • Seaborn (tested for 0.9.0)
  • lmfit (tested for 1.0.0)
  • PyPubSub (tested for 4.0.3)
  • Photutils (tested for 1.0.1)

We have detected a problem with older versions of Mac not working with newer versons of pip because it can not found any version of matplotlib avaliable, for this case it is recommended to create an enviroment with a pip version no more than 20.2.2.

How to install and execute

  1. Open the terminal and write pip install AstroCabTools
  2. Once all the libraries had been updated and the package installed, to execute each program, the next commands need to be written on the terminal:
  • bandChan to execute mrs_chan.
  • specChan to execute mrs_spec_chan.
  • detPlot to execute mrs_det_plot.
  • fitLine to execute fit_line.
  • cubeAns to execute cube_ans.
  • allTools to execute all_tools.

Manually installation

If your plan is to download from this repository and install it manually, execute pip install . inside the folder. Rather than using the python install, this makes all the packages to be installed in the same folder where the libraries can not find any problem of not finding libraries where they should be.

Development

To dos

New:

  • Fix PyQt5.sip error
  • Online documentation

Done:

  • mrs_chan features:

    • Specific wavelength location inside mrsSpec channels
  • mrs_spec_chan features:

    • Representation and management of spectra on a range of wavelength values
  • Representation of specific observed wavelengths selected on the plot

  • Representation of specific lines of interest from a list on the plot

  • Management of different specification ranges where each plot is going to appear

  • mrs_det_plot features:

    • Visualization of multiple .fits images
    • Management of the scale, stretch and colour of all the images
    • Visualization of values selected on an specified image along each axis
  • fit_line features:

    • Make gauss fitting model based on five points from an spectrum
    • Allow to make more than one gauss fitting model
    • Represent all gauss models
  • cube_ans features:

    • MIRI cube representation
    • Spectrum representation from an area selected
    • Creation of Annulus Background for subtraction from the initial area selected
    • Representation of the initial spectrum or the resultant from the subtraction in the fit_line tool
    • Obtain image based on the sum of flux for each pixel along a range of wavelength values
  • all_tools features:

    • Execute each one of the four programs independently
