Transiting Exoplanets - JWST NIRSpec
The observation modes available to observations of exoplanet is describe in the BOTS page.
For a description of the NIRSpec Exoplanet Exposure Time Calculator visit https://www.cosmos.esa.int/web/jwst-nirspec/neetc
The limiting magnitutude limits are presented here: https://www.cosmos.esa.int/web/jwst-nirspec/brightness-limits
Signal to noise ratios has been computed as a funtion of magnitude of the host star: https://www.cosmos.esa.int/web/jwst-nirspec/snr
And finaly, case studies conducted based on atmospheric models based on well known exoplanets: https://www.cosmos.esa.int/web/jwst-nirspec/case-studies
