J/ApJS/126/331 Spectrophotometry of Nearby Field Galaxies (Jansen+ 2000) ================================================================================ Spectrophotometry of Nearby Field Galaxies: The Data Jansen R.A., Fabricant, D., Franx, M., Caldwell, N. =2000ApJS..126..331J (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Galaxies, spectra; Galaxies, nearby; Equivalent Widths Keywords: atlases: galaxies - galaxies: fundamental parameters - galaxies: ISM - galaxies: stellar content - surveys Description: We have obtained integrated and nuclear spectra as well as U, B, R surface photometry for a representative sample of 196 nearby galaxies. These galaxies span the entire Hubble sequence in morphological type, as well as a wide range of luminosities (M_B = -14 to -22). Here we present the spectrophotometry for these galaxies. The selection of the sample and the U, B, R surface photometry is described in a companion paper (=2000ApJS..126..271J). The spectra span the range 3550 -- 7250 Angstrom at a resolution (FWHM) of ~6 Angstrom, and have an overall relative spectrophotometric accuracy of ~ +/- 6%. We present a spec- trophotometric atlas of integrated and nuclear rest-frame spectra, as well as tables of equivalent widths and synthetic colors. The spectra are available electronically at URL www.public.asu.edu/~rjansen/nfgs/ .

Trailing the table, notes or comments to that table may be present. Each of these lines starts with a pound-sign (#) and should be either ignored/skipped or stripped from the table on automated read-in. Although this is not conform the CDS standard my SM routines rely on their presence for automated read-in of the table data.

Nuclear [S II]6731 emission-line EW -------------------------------------------------------------------------------- Note on Balmer EWs (Hd, Hb, Ha, Hdn, Hbn, Han): EWs have been partially corrected for superposed stellar absorption due to the method of measurement. On average, in galaxies with (moderately) strong emission lines one may expect an additional 1.0{AA} in absorption in H{beta} ( 1.5{AA} in H{alpha} ) to be present. Note on all EWs: To conserve space and improve readability, positive numbers are used to indicate emission, contrary to convention. Typical measurement errors are plus-or-minus 3%-10% for strong emission lines, rising to plus-or-minus 30% for emission lines with EWs smaller than or equal to 2 Angstrom.

Note on all fluxes: Fluxes have NOT been corrected for interstellar reddening, neither in the foreground (Galactic) or internal to the galaxies themselves. Typical measurement errors are plus-or-minus 3%-10% for strong emission lines, rising to plus-or-minus 30% for emission lines with EWs smaller than or equal to 2 Angstrom.
