We release the first simulated images created with FORECAST (Fortuni et al. 2023), a flexible code for forward modeling of hydro-dynamical models using a particle-based method. This release consists of a field of view of ~200 sq. arcmin. mimicking the observation in 22 wide passbands: 7 from JWST NIRCam, 10 from HST, 4 from Spitzer, and 1 from Hawk-I Ks. The depths of the images are simulated consistently to the CANDELS GOODS-South (for HST, Ks and Spitzer) and CEERS (JWST) observed depths.
All the details about these images and the procedure used to create them can be found in the mentioned paper.
Three examples of small areas of the simulated FoV containing a single object or a small group of galaxies, in four out of the thirteen simulated bands (left to right: B435, Y105, H160, IRAC CH1, in μJ units). They are low-redshift sources, with z=0.35-0.45.
The dataset includes:
– the scientific images
– the corresponding RMS maps
– the PSFs used to create the images
– the input catalog containing “ground-truth” values of the simulated objects.
To obtain the dataset, please send an email to flaminia.fortuni@inaf.it with subject “FORECAST DR1”; you will receive a direct link to the on-line repository where the images are stored (password-protected). By doing so, you will also receive updates about new releases and/or code upgrades.
The code is available at the following link: FORECAST CODE, along with a user guide. If you have any questions, please feel free to contact us.
Please cite Fortuni et al. 2023 if you use (part of) this dataset/code for your science!
