J/ApJS/186/406           350um polarimetry from CSO              (Dotson+, 2010)

350µm polarimetry from the Caltech Submillimeter Observatory. Dotson J.L., Vaillancourt J.E., Kirby L., Dowell C.D., Hildebrand R.H., Davidson J.A. <Astrophys. J. Suppl. Ser., 186, 406-426 (2010)> =2010ApJS..186..406D

We give tabulated results and maps showing polarization vectors and intensity contours. The summary includes over 4300 individual measurements in 56 Galactic sources and two galaxies. Of these measurements, 2153 have P≥3σp statistical significance. The median polarization of the entire data set is 1.46%. Description: The instrument, calibrations, and data analysis techniques have been described in detail by Schleuning et al. (1997PASP..109..307S), Dowell et al. (1998ApJ...504..588D), and Kirby et al. (2005PASP..117..991K). Table 1 lists the coordinates, observing dates, peak intensities and size and range of directions of the chop used for each object. File Summary:

Note (1): Observing dates numbered as follows: 1 = 1997 April 18-27; 2 = 1997 September 18-26; 3 = 1998 February 14-19; 4 = 1998 May 2-3; 5 = 1999 January 27-30; 6 = 1999 April 4-8; 7 = 2000 January 4-8; 8 = 2000 July 24; 9 = 2001 February 21-26; 10 = 2001 April 10-16; 11 = 2001 July 19-20; 12 = 2002 February 14-18 Note (2): Flux into a 20" Hertz beam. Note (3): Reference or calibration source for intensity estimate. * 1 = Sandell, 1994MNRAS.271...75S * 2 = Andre et al., 1993ApJ...406..122A * 3 = Goldsmith et al., 1990ApJ...350..186G * 4 = Ladd et al., 1993AIPC..278..246L * Unreferenced objects are calibrated with respect to multiple sources observed with Hertz. These sources include W3(OH) (498Jy per 19.5" beam; Sandell 1994MNRAS.271...75S), Mars (brightness temperature 213K), and Uranus (brightness temperature 63K), and/or other objects in the table with known intensities. Note (4): "chopping" consists in rapid modulations (3-4Hz) of the secondary mirror to remove most of the atmospheric fluctuations (see text)

Note (1): oX is parallel to RA, except M17 is 16 degrees clockwise from RA and M82 is 24 degrees clockwise from RA. oY is parallel to Dec, except M17 is 16 degrees clockwise from Dec and M82 is 24 degrees clockwise from Dec. Pixel offsets in the x- and y-directions are given in units of the pixel center-to-center spacing, 17.8 arcseconds. Right Ascension and Declination offsets are calculated using this spacing and are rounded to the nearest arcsecond; offsets are given with respect to the object centers given in Table 1.
