VII/6 Polarization of Extragalactic Radio Sources (Eichendorf+ 1980) ============================================================================= Catalogue of Polarization Measurements and Related Data of Extragalactic Radio Sources Eichendorf W., Reinhardt M.=1979Ap&SS..61..153E Eichendorf W., Reinhardt M. =1980AcCos...9....7E ============================================================================ ADC_Keywords: Polarization - 655 ; Galaxies, radio - 320 ; Redshifts - 695 ; Galaxy catalogs - 330 Description: The catalog contains 510 extragalactic radio sources, and covers all polarization measurements from 1965 to the middle of 1974 and a few other radio and optical data for these sources. The typical observation error was in the range of 1-2 percent in 1965 and 0.5-1 percent in 1974. The selection criterion for sources was that polarization data should be available at least at three wavelengths for each source. This reduced the sample to 510 sources. The catalog includes observational data: classifications, Cambridge numbers, coordinates, degrees of polarization at various wavelengths, polarization angles at each wavelength, largest angular diameters, position angles, and redshifts. The catalog also includes derived data: rotation measures, linear source diameters, polarization angles at wavelength 0 cm, differences between position angle and polarization angle at 0 cm, spectral indices between each pair of successive wavelengths observed, and polarization indices between each pair of successive wavelengths observed.

This information is largely observational. In most cases observational data were not available at all wavelengths. In all files, whenever this is the case, the field will be blank. The first fields (bytes 1-16) are identical in all four files.

Note on PA-PolA: Difference between the position angle of the source and the polarization angle at lambda = 0 cm in degrees. Note on SI: The mean spectral index coefficient, found by regression, of the individual spectral indices. Note: All of these values were recalculated by the authors of the catalog even when accepted values already existed, because of the greater amount of data available to them. See Eichendorf and Reinhardt (1979) and Eichendorf and Reinhardt (1980) for discussions of how the recalculated mean spectral indices compare to the existing data. Note on PI: Analogous to the mean spectral index for flux densities, this is the coefficient found by regression from the individual polarization indices. Note (1): SI(*) The spectral index SI(*) defined by a power law in the flux density function S, where S = frequency . power(SI(*)). Usually SI(*) is notated with the greek letter alpha. The spectral index is determined only between the available wavelengths. Note (2): PI(*) The polarization index PI(*) is defined as a power law analogous to the spectral index for the flux density measurements. The degree of polarization, P = frequency. power(PI(*)). As in the case of the spectral index, PI(*) is defined only between certain wavelengths. This quantity was introduced and defined by the authors and included in the catalog. See both references for details of the derivation, justification, and implications of this parameter. ---------------------------------------------------------------------------- The Redshift-Corrected Data (datazcor.dat, File 3 of 4): For sources with a known redshift, the catalog authors corrected and rederived all wavelength-dependent values from the observed to the emitted wavelength. See Eichendorf and Reinhardt (1980) for a brief description of the process involved in correcting, interpolating, and rederiving values in the same wavelength standard. This file lists essentially the same data as the first file, except that any wavelength-dependent values have been redshift-corrected to the emitted wavelength. A computer program was then used to linearly interpolate the results back to the standard wavelengths. There are only 178 records, one object per record, in this file.

In addition, knowing the redshift and angular diameter, the additional parameter of linear source diameter was calculated. The model used was an open Friedmann universe with vanishing density, assuming the Hubble constant H=55 km/sec/Mpc See Eichendorf and Reinhardt (1980) for details of this calculation and a discussion of how redshift correction was applied and the results interpolated to determine both the spectral and polarization indices in the standard wavelengths chosen.

The original tape contained four text files formatted in the same manner as in the published catalog. The catalog was so well formatted that essentially no editing was required. Acknowledgements: The original ADC documentation by Theresa A. Nagy (1979) was used to generate this ReadMe file.
