The production rate of ionizing photons in young < 8 Myr, unresolved stellarclusters in the nearby irregular galaxy NGC 4214 is probed usingmulti-wavelength Hubble Space Telescope WFC3 data. We normalize the ionizingphoton rate by the cluster mass to investigate the upper end of the stellarinitial mass function (IMF). We have found that within the uncertainties theupper end of the stellar IMF appears to be universal in this galaxy, and thatdeviations from a universal IMF can be attributed to stochastic sampling ofstars in clusters with masses < 10^3 M_sun. Furthermore, we have found thatthere does not seem to be a dependence of the maximum stellar mass on thecluster mass. We have also found that for massive clusters, feedback may causean underrepresentation in Ha luminosities, which needs to be taken into accountwhen conducting this type of analysis.
