SimulatIONS of a DEEP FIELD program

We fave performed a set of simulations closely mimicking the deep spectroscopic observations part of the JADES survey, a joint effort of the NIRCam and NIRSpec GTO teams. The simulations are made possible by the NIRSpec Instrument Performance Simulator software, a Fourier Optics wave propagation module coupled with a detailed model of the instruments optical geometry and radiometric response, and a detector simulator reproducing the noise properties and response of NIRSpec's two H2RG sensors. The targets for the simulations were selected from the JWST Extragalactic Mock Catalog, JAGUAR.

A more extended description of the simulations is available in this document

Following a concerted team effort between NIRSpec GTO and STScI, these simulations have been made ready for processing by the STScI calibration pipeline. The simulations data set  can be found at the FTP server, here:
The products are described in the readme file at JWST_NIRSpec_Simulations/JADES_DEEP_JWST_release/README.txt and include:
  • A Jupiter notebook detailing the reduction of these frames from the second stage of the pipeline to fully calibrated products.
  • IPS-specific flat field files to produce calibrated data products (although see the README.txt file for caveats)
  • Independent reductions from the NIRSpec GTO pipeline
  • STScI pipeline-ready frames
  • STScI pipeline-reduced products
