我们目前的“快照”观测与近红外相机和多目标光谱仪（NICMOS）上的哈勃太空望远镜（HST）的94个附近的星系从修订的沙普利艾姆斯目录。在NICMOS相机3的51 "× 51“视场下，用两种滤光片获得了分辨率为0.”2的图像，一种是宽带连续滤光片（F160 W，大致相当于H波段），另一种是以Paα线为中心的窄带滤光片（F187 N或F190 N，取决于星系的红移）。进行一阶连续减法，并给出了由此产生的线图和积分Paα线通量。统计分析表明，早型（Sa-Sb）涡旋中心区域Paα表面亮度最高。
We present "snapshot" observations with the Near-Infrared Camera and Multi-Object Spectrometer (NICMOS) on board the Hubble Space Telescope (HST) of 94 nearby galaxies from the Revised Shapley Ames Catalog. Images with 0.″2 resolution were obtained in two filters, a broadband continuum filter (F160W, roughly equivalent to the H band) and a narrowband filter centered on the Paα line (F187N or F190N, depending on the galaxy redshift) with the 51′′ × 51′′ field of view of the NICMOS camera 3. A first-order continuum subtraction is performed, and the resulting line maps and integrated Paα line fluxes are presented. A statistical analysis indicates that the average Paα surface brightness in the central regions is highest in early-type (Sa-Sb) spirals.
