We produce an estimate for theK-Bessel functionwith positive, real argumentyand of large complex orderwhereris bounded andfor a fixed parameterorfor a fixed parameter. In particular, we compute the dominant term of the asymptotic expansion ofas. Whentandyare close (or equal), we also give a uniform estimate. As an application of these estimates, we give bounds on the weight-zero (real-analytic) Eisenstein seriesfor each inequivalent cuspwhen.
