The PDF linked above has a wealth of data. I pull out some of the graphics into this issue here as PNGs:

Temperature profiles

Zooming in on the top axis, it is difficult to see borehole labels:

Questions

[ ] All profiles appear 2x, starting near the same temperature and deviating at depth. Why? Which should we use?
[ ] On p. 58 there is mention of Camp VI EPF and Camp VI EPF, but there is no other mention of IV in the document. In thefigure, CVI EPF and CVI EGIG appear 2x. Is it possible there is a typo and one of these profiles is VI and one isVI`? Which is which?
[ ] P.N. is Punkt. Nord from p. 53 of the above document.
[ ] Mc. is Milcent from p. 53. - Closes #5
[ ] Site II is already in our DB. See https://github.com/GEUS-Glaciology-and-Climate/greenland_ice_borehole_temperature_profiles/tree/main/SiteII
[ ] St. C. is Station Centrale from p. 53 - Closes #9
[ ] Cr is Crête from p. 53 - Closes #4
[ ] J. J. is Jarl Joset from p. 53

@BaptisteVandecrux : Some new firn profiles here if you have not seen this document? See also 3 boreholes at #25

From translation (thanks to M. Lüthi) we only digitize + symbols: StationCentrale_EGIG, SiteII_EGIG, and CVI_EPF. These may be duplicates from Heuberger (1954) but are still useful at this point to digitize for quality control on the digitization process.

The above figure has all data on 10 m intervals, so even the Y axis (depth) from the digitization provides useful information about precision and accuracy.
