OH as a probe of the warm water cycle in planet-forming disks

This dataset includes selected portions of the MIRI-MRS and NIRSpec spectrum of the d203-506 disk analyzed in the paper by Zannese et al. (2024), to be published by Nature Astronomy. The original observational data are part of the Early Release Science program 'PDRs4All' (ID 1288) and are available on the MAST database https://archive.stsci.edu/. This release also contains the synthetic spectra used in the paper.

The dataset consists of five data files. The first file contains the observed spectrum, the continuum subtracted and the continuum+lines subtracted spectrum from MIRI-MRS of d203-506 in the 9-10.5 μm region shown in Fig. 2 of Zannese et al. (2024). The synthetic spectrum from GROSBETA which reproduces the observations corresponds to OH prompt emission following water photodissociation. The second file is the observed spectrum, the continuum subtracted and the continuum+lines subtracted spectrum from NIRSpec of d203-506 in the 2.84-3.25 μm region shown in Fig. 3 of Zannese et al. (2024).  The synthetic spectrum from GROSBETA which reproduces the observations corresponds to OH emission following its excitation from chemical ("formation")-pumping via O+H2. Fig. 2 and Fig. 3 of Zannese et al. (2024) can be reproduced using the two Python scripts.

The third file contains the observed spectrum and the continuum subtracted from MIRI-MRS of d203-506 in the 5.8-6.4 and 18-24 μm region shown in Extended Data Fig. 8 of Zannese et al. (2024). It also contains a RADEX model for H2O emission and a LTE model for CH3+.

The fourth file contains the full observed ON and OFF MIRI-MRS spectrum (not stitched). The fifth file contains the full observed ON and OFF NIRSpec spectrum.
