On-sky source templates for ScopeSim
Project description
This packages contain a number of templates to generate Source objects to be used in simulations with the ScopeSim Simulator
The Documentation can be found here: https://scopesim_templates.readthedocs.io/en/latest
Installation
The best way to install the software is to use pip
pip install scopesim_templates
To install the development version you can clone the repository
git clone https://github.com/AstarVienna/ScopeSim_Templates/
cd ScopeSim_Templates
pip install -e .
Requirements
The Source object
The above functions are created to easy the creation of standard sources but the power of the Source object doesn’t end there and can be used to create endless sources possibilities.
In a nutshell a Source object contains a spacial and spectral description of the sources. The spectral description are in the form of synphot spectra and the spacial description can be an astropy table referencing the spectra or a fits image. Source can also accept datacubes. The speXtra package contains an extensive library of spectral templates that can be used with the sources. Please check the relevant documentation.
Source templates included
Currently, the package covers the most typical sources used in astronomy:
- stellar
star: Places a single star on the field
stars: Places a list of stars on the field
star_field: Creates field of stars with random positions
star_grid: Creates a field of stars with regular positions
cluster: Creates an age=0 cluster with a user selected mass
- extragalactic
galaxy: A simple sersic model with a user selected SED from the speXtra database
galaxy3D: A more complex model that includes a velocity field and velocity dispersion field
spiral_two_component: Simple two component model with an outer spiral young SED and an old SED bulge
elliptical: Another sersic model using the Brown SEDs
- misc
point_source: similar to star but using any SED from the speXtra database
uniform_source: Creates a uniform source with any SED from speXtra
source_from_file: Load the source from a fits file. Depending on the characteristics othe functions may be more suitable
source_from_imagehdu: creates a source from an ImageHDU with an arbitrary flux and scale
source_from_imagehdu_with_flux: creates a source from an ImageHDU where the flux/pixel is known
source_from_array: General function to create a source from a 2D numpy array
source_from_cube: Wrapper to create a source from a 3D datacube
- calibration
lamp: Simulates a calibration lamp, i.e. a homogenous source with emissions lines
flat_field: Simulates a flat field
empty_sky: To simulate a sky without no other sources
Please see the documentation how to use each particular source and contact us (raise an issue or submit a pull request) if more specialized sources are needed.
