Index (links) for pieces that include tomographic data:
Whole pieces:
Piece #1. Ren1wcR45-Xtif8: This is a stack of tomography images of the whole piece, normal to X.
Ren1wcR45-Ztif8: This is a stack of tomography images of the whole piece, normal to X.
Ren1wc-R45c.nc: Volume data, cropped and rotated, from which stacks derive (netCDF format).
Ren1psA: Piece #1, polished section A. Numerous objects in this section are under study. Data for each is separated into different directories.
> BSE-TOMO comparison: Comparison of tomography data with BSE image and Mg-Ca-Al composite x-ray map.
> element maps: Raw element x-ray mosaics, Ren1psA.
> RGB tif files: Raw element x-ray mosaic RGB composites.
chondrule 1: Single chondrule separated 'virtually' from tomographic data, then cut from a subsection of the volume. Surface chemical data is in several forms.
chondrule 3: Single chondrule separated 'virtually' from tomographic data, then cut from a subsection of the volume. Surface chemical data is in several forms.

This piece (tomo pc. 1) has been cut into three sub-sections: A, B, C.
Piece #2. Three serial surfaces have been cut and polished:
> Piece #2, polished section 1.
> Piece #2, polished section 2.
> Piece #2, polished section 3.

PTS588-2: Polished thin section AMNH 588-2.
> Mg-Ca-Al=RGB: A composite x-ray map (red-green-blue, RGB) where the channels are: Mg=red, Ca=green, Al=blue. (150 dpi, RGB)
> Si-Ca-Fe=RGB: A composite x-ray map (red-green-blue, RGB) where the channels are: Si=red, Ca=green, Fe=blue. (150 dpi, RGB)
> element maps: Raw element x-ray mosaics. The x-ray maps for each element have each been normalized to the same grayscale range to appear as seamless as possible. These maps are all registered exactly the same, so they overlap perfectly.
Interested viewers can aply their own, preferred color scheme to make RGB composites.
> RGB tif files: Raw element x-ray mosaic RGB composites. For each file, the elements in RGB channels are listed in order (e.g., SiCaNi, NiS-Fe).
