N2 - We present a catalogue of 22 755 objects with slitless, optical, Hubble Space Telescope (HST) spectroscopy from the Grism Lens-Amplified Survey from Space (GLASS). The data cover similar to 220 sq. arcmin to 7-orbit (similar to 10 ks) depth in 20 parallel pointings of the Advanced Camera for Survey's G800L grism. The fields are located 6 arcmin away from 10 massive galaxy clusters in the HFF and CLASH footprints. 13 of the fields have ancillary HST imaging from these or other programs to facilitate a large number of applications, from studying metal distributions at z similar to 0.5, to quasars at z similar to 4, to the star formation histories of hundreds of galaxies in between. The spectroscopic catalogue has a median redshift of = 0.60 with a median uncertainty of Delta z/(1+z) less than or similar to 2 per cent at F814W less than or similar to 23 AB. Robust continuum detections reach a magnitude fainter. The 5 sigma limiting line flux is f(lim) approximate to 5x10(-17) erg s(-1) cm(-2) and half of all sources have 50 per cent of pixels contaminated at less than or similar to 1 per cent. All sources have 1D and 2D spectra, line fluxes/uncertainties and identifications, redshift probability distributions, spectral models, and derived narrow-band emission-line maps from the Grism Redshift and Line Analysis tool (GRIZLI). We provide other basic sample characterizations, show data examples, and describe sources and potential investigations of interest. All data and products will be available online along with software to facilitate their use.
