Getting Started
Tools to help the community with planning exoplanet observations.
PandExo is both an online tool and a python package for generating instrument simulations of JWST’s NIRSpec, NIRCam, NIRISS, and MIRI, and HST’s WFC3. It uses throughput calculations from STScI’s Exposure Time Calculator, Pandeia: Pandeia + Exoplanets = PandExo. This documentation contains information on how to download, install and analyze PandExo output.
Try PandExo online through the STScI ExoCTK website.
Should I install PandExo or use the online interface?
Install if…
I will be using PandExo for more than 10 runs
I want to submit bash runs
I want to use the online GUI but don’t want to be subject to any slow downs because of high user frequency
I want to be able to use plotting functions to analyze my output
Install EVEN if…
I am scared of Python
Do not install if…
I will only be using PandExo fewer than 10 times
Requires
Python >=3.10
Installation: https://natashabatalha.github.io/PandExo/installation.html
PandExo requires downloading reference data for 1) JWST instrument info (from Pandeia), 2) JWST PSFs, 3) stellar SEDs used by synphot/stsynphot, and 4) normalization bandpasses. It also requires setting up
pandeia_refdata,PSF_DIR, andPYSYN_CDBS. See installation for further instructions: https://natashabatalha.github.io/PandExo/installation.html
