Turning citations into ADS links

Citation linking.   My latex and bibtex example defines and uses \citeads etc. latex citation commands (“macros”).  These turn citations within the text into links that open the corresponding ADS abstract pages in the browser (if your pdf reader permits web access, as do the chrome and firefox pdf viewers, evince, xpdf, macOS Preview.  In Adobe Acrobat/Reader adjust Edit > Preferences > Trust Manager > Change Settings).  Such one-click/tap ADS page opening is convenient in on-screen article or manuscript inspection because it shows the abstract and links to the full article in parallel to one's reading, without jump to the reference list as happens with most hyperlinked journal files.  Instead, you stay where you are in your publication reading. 

In addition, these commands together with a modified .bst style file can add ADS links to the references.

These commands require that you use separate \citeads commands per cited article using its ADS bibcode label.  My example.tex also shows how to treat sequences as Vernazza et al. (1973, 1976, 1981).  Using ADS bibcodes as \cite labels is a good idea anyhow when working with collaborators to avoid label mixups and confusion as to which article is meant.

This latex trick survives the pdf generation by arXiv (Astroph).  It also survives A&A production and is recommended in EDP's readme.txt for A&A authors (but use the macros in example.tex which are adapted to “new” ADS).  Unfortunately, this trick does not survive ApJ's conservative editorial processing before the IoP production (while it does for other IoP journals).  Reversely, for Solar Physics it survives editorial processing but not the nasturtium-prone Springer production.

Page linking.  A similar latex trick is the addition of links to open specified figures, tables, equations etc in cited publications.  The macro is also given in example.tex.  Rather like clicking/tapping blue items in Wikipedia pages to open the pertinent page directly, instead of the usual roundabout publisher way of jumping you to the reference list when you click/tap a citation, to let you find the ADS link there (if present), use that to open the pdf via ADS (if you are licensed), yet more roundabout for silly publishers via their website (even if you are licensed), flip through its pages to find the specified one, finally inspect the cited item - while with the jump and all this clicking/tapping you lost the sentence and page that you were reading and may have trouble returning there.  Wikipedia-style direct page opening is much better!  Example: when clicking/tapping Fig. 3 in “See Fig. 3 of Rutten et al. 1991” in a publication pdf made with this macro this direct linker opens the very page with that figure in your browser so that it can be inspected in parallel with the publication, not disturbing its reading. 

ADS taught me this trick in 2016 and made it survive its 2019 “classic” to “new” transition.  It also survives arXiv and A&A pdf production, and can even survive at Springer. It works with the ADS bibcode for most publications with a full-text publisher pdf-symbol button with a green open-access dot on ADS serving the pdf directly.  A&A and ApJ yielded such buttons after one year, from 2022 directly. MNRAS does after three years. Springer publications never do even when they are open access.  When there is none you may use the ADS altcode for the arXiv version (also shown in example.tex) but often the classic ADS page opener does this itself.

This pdf page opening is handled correctly by Adobe Acrobat/Reader, evince, xpdf, the chrome and firefox pdf viewers and other pdf readers, but macOS users (including Preview) may be shunted instead to the start page.
