| 2025-03-17 | roman_0079.pmap | archived | This is the updated skycell reference file for the Roman Telescope adopting a tessellation scheme of the celestial sphere to obtain mosaics stored in the Roman archive. This tessellation partitions the sphere in 4058 sky tiles whose centers and limits in declination are defined by a Healpix double tessellation scheme with N side equal to 13. See Roman-STScI-000708 technical report from D. Radda et al entitled The Roman tessellation of the celestial sphere. |
| 2025-03-13 | roman_0078.pmap | archived | Simulated point spread functions PSFs made using stpsf version The PSFs are stored in a dimensional array corresponding to focus spectral type grid position y x where the focus is the number of defocus waves in stpsf or or and corresponds to in focus spectral type is in order of A V G V and M V and grid position is an index related to the meta pixel x and meta pixel y values in the file metadata |
