I am using aastex class with twocolumn option for an article.
\documentclass[twocolumn,linenumbers]{aastex61}
I want my first section to start right after the abstract which is in a single-column format. I tried the multicol option but it is not recognized. I have also tried this solution, which gives me error in the \twocolumn[ usage. How can I fix that?
aastexis meant for submissions to journals of the American Astronomical Society; they decide how a paper should be typeset. Withaastex62, I get the expected output. – egreg Sep 27 '18 at 17:31
