Title: Rotation Measures of Extragalactic Sources Behind the Southern Galactic Plane: New Insights into the Large-Scale Magnetic Field of the Inner Milky Way Authors: Brown J.C., Haverkorn M., Gaensler B.M., Taylor A.R., Bizunok N.S., McClure-Griffiths .M., Dickey J.M., Green A.J. Table: Rotation Measures of the SGPS ================================================================================ Byte-by-byte Description of file: datafile1.txt -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1- 6 F6.2 deg GLON Galactic longitude (1) 8- 12 F5.2 deg GLAT Galactic latitude (1) 14- 15 I2 h RAh Hour of Right Ascension (J2000) 17- 18 I2 min RAm Minute of Right Ascension (J2000) 20- 23 F4.1 s RAs Second of Right Ascension (J2000) 25 A1 --- DE- Sign of the Declination (J2000) 26- 27 I2 deg DEd Degree of Declination (J2000) 29- 30 I2 arcmin DEm Arcminute of Declination (J2000) 32- 33 I2 arcsec DEs Arcsecond of Declination (J2000) 35- 38 I4 mJy I Peak-pixel interferometric Stokes I value 40- 43 F4.1 % m Fractional polarisation (2) 45- 49 I5 rad/m2 RM Faraday rotation measure 51- 52 I2 rad/m2 e_RM Uncertainty in RM 54 A1 --- f_RM [d] Flag on RM (3) -------------------------------------------------------------------------------- Note (1): The identified location is the peak of the gaussian fit to the source in polarised intensity. All sources were either unresolved or partially resolved. Note (2): Linear polarised intensity divided by Stokes I averaged over the FWHM pixels used for rotation measure calculation. Note (3): d = A RM for this source was calculated by Gaensler et al. (2001) using a simpler approach than the more rigorous method used here. These new values should replace the previously determined values. -------------------------------------------------------------------------------- 253.30 0.89 08 19 46.2 -34 42 05 179 5.8 -8 12 253.52
