cds-question@unistra.frgalaxy-clustersredshiftedline-intensitiesWe present H{alpha}-derived star formation rates (SFRs) for the galaxy cluster Cl J0023+0423B at z=0.845. Our 3{sigma} flux limits correspond to an SFR of 0.24h_100_^-2^M_{sun}_/yr, and our minimum reliable H{alpha}+[NII] equivalent width is greater than 10{AA}, demonstrating that near-infrared narrow-band imaging can sample the star-forming galaxy population in distant clusters. Comparison with spectroscopy shows that the number of false detections is low (9%+/-6%) and that our H{alpha} equivalent widths are correlated with spectroscopically determined [O II] equivalent widths. A magnitude-limited spectroscopic survey conducted over the same area missed 70% of the star-forming galaxies and 65% of the integrated star formation. Using Hubble Space Telescope Wide Field Planetary Camera 2 Archive images, we fit Sersic profiles to all galaxies with significant narrow-band equivalent widths and find that equivalent width decreases as the steepness of galaxy profile increases.2004ApJ...604..141Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/604/141CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/AJ/116/560 : Cl J0023+0423 and Cl J1604+4304 spectroscopy (Postman+ 1998)J/AJ/116/584 : Cl J0023+0423 and Cl J1604+4304 morphology (Lubin+ 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/604/141https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/604/141http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/604/141https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/604/141https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/604/141http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/604/141GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJ/604/141/table2Data for CL J0023+0423B galaxiesn?
