How To Install python3-pysynphot on Ubuntu 18.04
Introduction
In this tutorial we learn how to install python3-pysynphot on Ubuntu 18.04.
What is python3-pysynphot
python3-pysynphot is:
pysynphot simulates photometric data and spectra as they are observed with the Hubble Space Telescope (HST). Passbands for standard photometric systems are available, and users can incorporate their own filters, spectra, and data. pysynphot user interface allows you to:
- Construct complicated composite spectra from various grids of model atmosphere spectra, parameterized spectrum models, and atlases of stellar spectrophotometry.
- Simulate observations.
- Query the resulting structures for quantities of interest, such as countrate, effective wavelength, effective stimulus, as well as the wavelength and flux arrays.
- Plot HST sensitivity curves and calibration target spectra.
- Compute photometric calibration parameters for any HST instrument mode.
pysynphot can help HST observers to perform cross-instrument simulations, to examine the transmission curve of the HST Optical Telescope Assembly (OTA), and spectra of HST calibration targets. Expert users can take advantage of the control and data structures available in Python 3 to easily perform repetitive operations such as simulate the observation of multiple type of sources through multiple observing modes.
There are three methods to install python3-pysynphot on Ubuntu 18.04. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.
Install python3-pysynphot Using apt-get
