This pages illustrates some of the galaxies with close pairs which we identified in our study of star formation in interacting galaxies selected from the Sloan Digital Sky Survey (Nikolic et al 2004, see the publication list ) . ... This is 10 out of 114 of all of the galaxies in the volume limited sample at redshift smaller than 0.03 and with the first companion within 30 kiloparsecs. A gallery of interacting galaxies . ...

... rgsbadpix combines the calibration bad pixel data from the CCF with any hot pixels found by analyzing the raw telemetry for one CCD from an RGS exposure in spectroscopy mode. ... When the same bad pixel is identified by both the CCF and the telemetry analysis, the output bad pixel table mentions only the CCF version. CCF bad pixels that lie outside the telemetry window of the exposure are not included. ... A bad pixel identified by analysis of the telemetry. ...

Next: Non-classified objects Up: Non-emission-line objects Previous: Absorption-line galaxies . To separate the stars among the objects missing detectable emission lines we cross-correlated a list of the most common stellar features with the observed spectra. ... All of them were crudely classified in categories from definite A-stars to G-stars, with most of them intermediate between A and F. The data for these stars are presented in Table 7. ... 2001-06-08 ...

Automatic Classification of Sunspot Groups Using SOHO/MDI Magnetogram and White Light Images David Stenning March 29, 2011 1 Introduction and Motivation Although solar data is being generated at an unprecedented rate, the majority of sunspot classification is done manually by experts. ... This is to smooth the "white" areas in the magnetograms. ... Left: Inverse Magnetogram Right: "Opened" Inverse Magnetogram 6 Using the cleaned images, sunspot active-region "seeds" are obtain by thresholding. ...

Next: Sample Properties Up: Sample Identification Previous: Comments on Individual Sources . Previously known serendipitous sources were selected by cross-correlating WGACAT with a variety of optical and radio catalogs, including the Ver?n-Cetty & Ver?n (1996) and Hewitt & Burbidge (1993) quasar catalogs, the 1 Jy (Stickel et al. 1994) and S4 (Stickel & K?hr 1994) radio catalogs, and the BL Lac catalog of Padovani & Giommi (1995b). ... Details of these 97 objects are given in Table 6. ...

... Chapter 4: Solar System Targets > 4.2 Target Identification . ... The following information is required to identify and classify each target. ... For example, separate targets should be defined if you plan to take spectra of several different surface features on a planet, or if you plan to observe the same feature with different timing constraints. ... Description . PLANET . If the target is the center of a planet, enter PLANET followed by its name (e.g., PLANET JUPITER , PLANET SATURN ). ...
