PandExo generates instrument simulations of JWST’s NIRSpec, NIRCam, NIRISS and NIRCam and HST WFC3 for planning exoplanet observations. It uses throughput calculations from STScI’s Exposure Time Calculator, Pandeia, and offers both an online tool and a python package.
Exo-MerCat generates a catalog of known and candidate exoplanets, collecting and selecting the most precise measurement for all interesting planetary and orbital parameters contained in exoplanet databases. It retrieves a common name for the planet target, linking its host star name with the preferred identifier in the most well-known stellar databases, and accounts for the presence of multiple aliases for the same target. The code standardizes the output and notation differences and homogenizes the data in a VO-aware way. Exo-MerCat also provides a graphical user interface to filter data based on the user's constraints and generate automatic plots that are commonly used in the exoplanetary community.
VSPEC (Variable Star PhasE Curve) simulates exoplanet observations. It combines NASA’s Planetary Spectrum Generator (PSG) with a custom variable star model. Originally built to simulate the infrared excess of non-transiting planets, VSPEC supports transit, eclipse, phase curve geometries as well as spots, faculae, flares, granulation, and the transit light source effect.
