Observing in a pure parallel mode throughout HST Cycles 12 and 13, our survey covers ∼104arcmin2 from which we select 80 galaxies with likely redshifted Hα emission lines. In several cases, a somewhat weaker [OIII] doublet emission is also detected. Description: All of the data presented in this study have been obtained using camera 3 of NICMOS onboard HST, taken in the pure parallel mode with the G141 grism and the broadband F110W/F160W filters, between 2003 October and 2004 July (Cycle 12), 2004 July and 2005 January (Cycle 13).

Note (1): We assign the suffix a, b, or c to identify different objects in one field. Note (2): 'e' indicates objects that do not have either F110W/F160W photometry are objects lying near the image edge. Due to the locations, we could not find these objects in the direct image despite of clear emission lines (not thought to be zero order) for these galaxies. All galaxies without F110W photometry do not have the corresponding F110W images, i.e., there is no F110W-dropouts or galaxies with very red (F110W-F160W) colors. Note (3): In general there is a systematic redshift determination error of Δz∼0.03. Also, there are a few cases where the emission-line object lies near the edge of the image. In these cases, the counterpart of the object is not found in the associated direct image, which causes a large uncertainty in wavelength calibration up to ∼0.1um. The redshift uncertainty for an object lying at the image edge is Δz∼0.15. Note (4): Since the [NII] and Hα lines are not resolved in the resolution of NICMOS grism, FHa represents f(Hα+[NII]). Expressed in 10-16erg/cm2/s. Note (5): F110W/F160W magnitudes are in AB magnitudes, MAG_AUTO from SExtractor (total magnitudes of the galaxies). The conversion between AB and Vega magnitudes are F110WVega=F110WAB-0.73; F160WVega=F160WAB-1.31 (derived using NICMOS zeropoints in Vega magnitude system at http://www.stsci.edu/hst/nicmos/performance/photometry/postncs_keywords.html). Note (6): Hα luminosity and the derived star formation rate are corrected for possible [NII] contamination in the measured Hα line flux: f(Hα)=0.71*f(Hα+[NII]).
