Image data of bright deposits in permanently shadowed craters on Ceres

These are image data described in "Spectral properties of bright deposits in permanently shadowed craters on Ceres" by Schröder et al., published as Astronomy & Astrophysics 688 (2024) A178, doi:10.1051/0004-6361/202450247. The data correspond to the permanently shadowed craters on Ceres shown in Figs. 2 to 6 in the paper.

There is a data set for each of the following permanently shadowed regions: NP04, NP05, NP07, and SP01. Each data set consists of 4 parts: (1) unprojected images in IMG format (header + binary), (2) unprojected images in FITS format, (3) projected images in IMG format, and (4) projected images in FITS format. The images contain reflectance values (I/F) in floating-point format. They are corrected for in-field stray light and have been registered to a global shape model to correct minor pointing errors. The data files are equipped with a rudimentary header.

File name syntax: In "FC21B0045550_15282040820F2D.IMG", "FC2" is the camera model, "45550" is the image number, and "F2" is the filter.
