论文摘要

我们介绍了3163个晚期型螺旋形的延长旋转曲线的光度法和旋转曲线观测值(探针)汇编(探针),其中1677个均匀的多型光度法匹配。探针旋转曲线最初是从HALPHA长缝光谱和孔径合成HI(21cm)速度映射中提取的,通常延伸到中间2R_E(或1R_ {23.5,r})。我们均匀的光度法利用了巨大的desi-lis和智慧图像以及软件自动化,可以产生多台和方位平均的表面亮度,使深度大于25 mag/arcsec^2(fuv,nuv),27 mag/mag/arcsec^2(g,r)(g,r)和26 mag/arc/arcsec^2(zsecsec^2(zsec^2(z),多功能探针数据集凭借其空间解析的曲线和广泛的结构参数表,将有益于银河系结构和形成的研究。

We present the Photometry and Rotation Curve Observations from Extragalactic Surveys (PROBES) compendium of extended rotation curves for 3163 late-type spirals, with matching homogeneous multiband photometry for 1677 of them. PROBES rotation curves originally extracted from Halpha long-slit spectra and aperture synthesis HI (21cm) velocity maps typically extend out to a median 2R_e (or 1R_{23.5, r}). Our uniform photometry takes advantage of GALEX, DESI-LIS, and WISE images and the software AutoProf to yield multiband azimuthally averaged surface brightness profiles that achieve depths greater than 25 mag/arcsec^2 (FUV, NUV), 27 mag/arcsec^2 (g, r), and 26 mag/arcsec^2 (z, W1, W2). With its library of spatially resolved profiles and an extensive table of structural parameters, the versatile PROBES data set will benefit studies of galaxy structure and formation.
