Getting started

Because we like to study historic inks in our lab, my colleague Birgit Reissland prepared an artificially aged blind test sample with inks on paper. A detail (see image below) with iron-gall ink was scanned with the Crono MA-XRF instrument and saved with the awkward file name starting with the hour time stamp 14:20:02 by the Crono software:

'14200215102021-blindTest2AgedDetail.HDF5' (50.6Mb).

In this tutorial we will explore and process the contents of this Crono HDF5 file.

If you want to try using the cronomaxrf package, you can download this small demo dataset from my Backblaze cloud storage by running the code below. Alternatively, you can manually download the HDF5 and image file by clicking on the links here: Crono HDF5 and png image.

from cronomaxrf.data import download

Ready!

Also included in the demo dataset is (2) a photo of the scan area.
