Carbonate spectra and Melilite overtone spectra from "Sakurai's Object revisited: new laboratory data for carbonates and melilites suggest the carrier of 6.9- μm excess absorption is a carbonate"

Carbonate and Melilite OVERTONE SPECTRA from  Bowey, J. E., Hofmeister, A. 2022 MNRAS, 513, 1774.  https://doi.org/10.1093/mnras/stac993

"Sakurai's Object revisited: new laboratory data for carbonates and melilites suggest the carrier of 6.9- μ m excess absorption is a carbonate"

Carbonate spectra in Fig 1 (carbonates.pdf) are in 2 column ascii files:  

calcite_verythin.tau, calcite.tau, dolomite.tau, magnesite.tau

True Meliliate overtone spectra in Fig 3 (goodmeliliteovertones.pdf are in 2 column ascii files:  

Ak70_135micron_chip.tau,  Ak70_120micron_chip.tau, Ak70.tau, Ak13.tau

The column 1 increment varies between files.

column 1 (x) is in increasing wavenumber (cm^-1)

column 2 (tau) is absorbance in optical depth units per micron thickness of sample.
