ABSTRACT. This catalogue is a compilation of all the data of linear polarization of radio sources published prior to December 1978. The catalogue contained 7225 data for 1510 radio sources. Polarization parameters derived from the data are also tabulated with other physical parameters.

Key words: Linear polarization - Radio source - Rotation measure - Depolarization.

1. Introduction

Measurements of linear polarization from radio sources have been extensively made at various wavelengths, but the data are inconveniently scattered over a great number of publications.

It is necessary to combine all these data to calculate the rotation measure and depolarization of radio sources, which are important for the investigation of the physical condition in the radio sources and of the space between the sources and the observers (e.g. Gardner and Whiteoak 1963; Sofue et al. 1968; Kronberg et al. 1972; and Morris and Tabara 1973). Entries in the catalogue are 1510 radio sources containing the data published prior to December 1978. The all of the quoted values with occasional negative numbers for the position angle of polarization are taken from the original references. The result of analysis of these data will be presented elsewhere.

2. The data of linear polarization

The observational results of linear polarization of radio sources are listed in Table 1. The sources are listed in order of increasing right ascension.

Column 1: source name.
Column 2: the wavelength in cm. In the case of radio sources resolved in two or three components, the data for the individual components are also listed after the data of the integrated polarization. The symbols W, E, N, S, and C at the head of the column denote the west, east, north, south, and central component, respectively.
Column 3: the percentage polarization (P) and its error (dP).
Column 4: the position angle of polarization (PA) and its error (dPA).
Column 5: notes on the references. See the corresponding number in the note to Table 1 next to Table 3.
Some observations of the linear polarization are monitors of the time variation. In these cases the data are given by averaging over the whole period and are denoted by an asterisk in column 5 of Table 1. Table 2 lists the sources which show apparently time variation in the linear polarization. Columns 1 and 2 show the source name and another well-known name. Column 3 gives the monitored wavelengths at which the source is recognized to be obviously variable. Column 4 gives note on the references that is the same as the column 5 of Table 1.

3. Source characteristics

The radio and optical characteristics of the radio sources listed in Table 1 are given in Table 3. To determine the polarization parameter, we have used the data in Table 1 except for the data published prior to 1964 and reference 27 on the ground that some of the data have large or systematic errors.

Column 1: source name.
Columns 2-5:alternate source name.
Columns 6,7:the radio position for epoch 1950, but in a few cases with an asterisk, the optical position.
Columns 8,9:the galactic coordinates of the source.
Columns 10,11:the source identification and optical magnitude. The source with an asterisk is variable in magnitude.

    QSO: quasi stellar object
    GAL: galaxy
    SNR: supernova remnant
    HII: H II region

Column 12: redshift.
Column 13:radio flux densities in Jy (= 10^26 W/Hz/m^2) at 6 cm. The sources with an asterisk are variable.
Columns 14-16:the values of rotation measure (RM) and its error in red/m, the intrinsic position angle (IPA) and its error in degrees, and the grade of these values. The RM and IPA are defined as phi(lam) = RM lam^2 + IPA, where phi(lam) is the position angle at the wavelength lam (Gardner and Whiteoak 1963). The method of calculation of RM is given in the next section.
Columns 17,18:the maximum degree of polarization and the depolarization wavelength in cm at which the percentage polarization drops to half its maximum value (e.g. Kronberg et al. 1972) The values are estimated graphically.
Columns 19-22:notes on the references corresponding to the radio position, optical identification and optical magnitude, redshift, and radio flux density. See the note to Table 3.

4. Calculation of rotation measure

For the calculation of RM, the sources with position angle observed at more than two distinct wavelengths between 6 and 31 cm were selected. The calculation was performed by a weighted least-squares fit to a straight line. The weighting factor of PA was the square of its error dPA. For sources without data for dPA, we estimated dPA using P and AP by the following formula, dPA = 0.5 * atan(dP/P). The fitting was made for all possible choices of +n*180 degrees ambiguities (n = 0,+/-1,+/-2,...) of PA.

The range of RM search was less than 200 rad/m^2 except at low galactic latitudes (cot |b| < 2, or |b|<26.5 degs), where the range was extended to 100 cot |b| rad/m2 in consideration of the contribution of our galactic disk. Goodness of fit was tested by the chi-square (chi2) method and the values of RM and IPA in Table 3 are given in the case that the integral probability P(chi2,v) is the highest, where v = N-2 is the number of degree of freedom left after fitting N data points to the two parameters of RM and IPA. As shown in column 16 of Table 3, sources are classified into three grades according to their integral probability P(chi2,v). Let P1 and P2 be the probabilities for the maximum and the second maximum values of P(chi2,v). Sources of grade A have P1/P2 >= 10 and P1 >= 20%, and that of grade B the same but 1%< P1< 20%. The remainder, e.g. 1% <P1 or P1/P2 < 10 are more ambiguous in the value of RM than that of grade A and B. and we give no mark in column 16 of Table 3.
