Change units from \"\" to null
Addresses #25 (closed) - some dimensionless units are listed as ""
, others as null
.
For the majority of files, null
is used (those with ""
are calibration devices and site parameters only). Changed therefore these files to null
.
We are still not entirely consistent for now, as there are occasions of
"unit": ", ",
"unit": ", , , , , ",
"unit": ", , cm, , ",
"unit": "cm, deg, , ",
"unit": "deg, , deg",
"unit": "deg, deg, , ",
De we want in all cases move to explicitly say null
? It is more consistent, but I think already now it is clear that those values are dimensionless.
