Thermoluminescence and Apollo 17 ANGSA lunar samples: NASA's fifty-year experiment and prospecting for cold traps

This data archive contains all thermoluminescence glow curves for this study.

The 'glowcurve_database.csv' file contains all glow curves, which are named by the data of aquisition, with the comma seperating the number of the glow curve for that date. For each glow curve, we provide the following four columns: (1) timestamp_sec, which is the epoch timestamp of data point; (2) elapsed_sec, which is the time in seconds since starting to record the data; (3) temp_c, which is the sample temprature in degree celsius; and (4) intensity_cps, which is the intensity of the loght measured in counts per second.

The 'glowcurve_metadata.csv' file provides the information about the sample and the instrumental settings for which the glow curve was obtained. The metadata headers are: (1) Filename, which is the glowcurve number; (2) sample, which is the sample number: (3) pan, which is the number of the glow curve pan used for this sample; (4) mass, which is the mass of the sample weighed into the pan in milligram; (5) measurement, which specifies if this is natural TL, or induced TL (exposure to 90Sr beta radiation for specified amount of time, usually 3 minutes), or black body measurement; (6) the PMT scale (i.e., 'gain') of the photomultiplier tube in scientific expression. Glow curve measurments at different scale or gain settings need to be corrected for glow curve intensity camparison (i.e.. multiply by scale or normalize to one scale setting). 

The 'glowcurve_printout_metadata_pdf' provides pdf files of all glow curves, which contains a printout along with the metadata. Therefore, the pdf files do not provide any additional or new information beyond 'glowcurve_database.csv' and 'glowcurve_metadata.csv' files.

We also provide indivual glow curve files in the 'glowcurves_individual.zip' archive.
