NASA/ADS citations not working

[AstroMike]

Hi Erik

When I right-click and select Citation counts I can get Inpsire/CrossRef and Semantic Scholar citations but when I try NASA ADS it always says "NASA ADS citation counts updated for 0 items" and nothing is altered in the Extra field. Whereas the others say "... updated for 1 items" and I see the Extra field updated.

@AstroMike I confirm the problem. NASA ADS requires a login and a token ("password") to use their API (the web site itself doesn't). I will have to add code to read the token from a file, and add instructions for people how to create such a token on the NASA ADS web site and put it into a file.
