We present a description of the CL-based package XDSPRES, which aims at being a complete reducing facility for cross-dispersed spectra taken with the Ohio State Infrared Imager/Spectrometer, as installed at the SOAR telescope. This instrument provides spectra in the range between 1.2um and 2.35um in a single exposure, with resolving power of R ~ 1200. XDSPRES consists of two tasks, namely xdflat and doosiris. The former is a completely automated code for preparing normalized flat field images from raw flat field exposures. Doosiris was designed to be a complete reduction pipeline, requiring a minimum of user interaction. General steps towards a fully reduced spectrum are explained, as well as the approach adopted by our code. The software is available to the community through the web site http://www.if.ufrgs.br/~ruschel/software., 14 pages, 10 figures

CCD frames in the B, V, R, and I passbands were obtained for the nearly edge-on spiral galaxy NGC 6835. The frames were analyzed to derive standard geometric and photometric parameters as well as luminosity and color distributions. The analysis of the luminosity profiles shows the existence of a flattened bulge and an exponential disk. The face-on parameters of the disk were obtained from a fit of an exponential disk seen edge-on to the observed data. The distribution of color indices along the major axis shows a pronounced blue gradient toward the nucleus, which we interpreted as a region of recent stellar formation.

In a former note (Sersic and Pastoriza 1965) we published the results of a survey of bright southern galaxies which were inspected for peculiarities in their nuclei. Although the sample was small ( 35 galaxies) it suggested a relationship between the existence of a bar and the presence of abnormal features in their nuclei. One of us (J.L.S.) had the opportunity* of extending the survey to the whole sky by inspecting the Hubble plate collection at Pasadena. The present discussion will be restricted to galaxies brighter than 11.0 photographic total magnitude (de Vaucouleurs 1963) in order to include in the sample the objects previously found in the southern sky. From 174 galaxies brighter than rnr = 11.0, 20 were found to have peculiar nuclei and are listed with magnitudes and morphological types in Table I. In order to avoid selection effects because of low-latitude obscuration and edge-on galaxies showing no nucleus, we retain only the 136 galaxies with latitudes higher than 20° and minor to major axis ratios b/a larger than 0.4. The values of b/a were deduced from the Reference Catalogue of Galaxies (de Vaucouleurs and de Vaucouleurs 1964 ) . As 20 galaxies with peculiar nuclei remain after this selection, the fraction of the sample with peculiar nuclei amounts to 14%.
