The GRIsm ACS Program for Extragalactic Science (GRAPES) achieves continuum detection as faint as zAB=27.2 using 40 orbits (9.2×10^4 seconds) on HST. The data were taken at four orientation angles to correct for the overlap of spectra. GRAPES data provide a unique, uninterrupted, low resolution (R=100) spectral coverage for 5500Å<λ<10500Å, and allow us to detect high redshift galaxies at 4<z<7 whether they have $\\lya$ lines or just show the Lyman Break, as well as find low luminosity AGNs in an unbiased fashion. This paper describes in detail the observations and the data reduction, and examines the quality of the extracted spectra. Subsequent papers will deal with the analysis of the data. The extracted and calibrated GRAPES spectra will be available from MAST at STScI."}],"article_processing_charge":"No","_id":"17726","extern":"1","volume":154,"title":"GRAPES, grism spectroscopy of the hubble ultra deep field: Description and data reduction"}
