几个具有线性极化观测能力的毫米波和亚毫米波设施在过去几年中已经开始运行。这些设施，以及其他以前的毫米望远镜和干涉仪，需要明亮和稳定的线性偏振校准器来校准新仪器和监测其仪器偏振。目前数量有限的足够的校准意味着困难，在收购这些校准observations.AimsLooking额外的线性偏振校准器在毫米光谱范围内，我们开始监测3C 286在2006年中期。这个源是一个标准的和高度稳定的偏振校准无线电observation.MethodsHere，我们提出了3毫米和1毫米监测观测之间获得的2006年9月和2012年1月与XPOL偏振仪的IRAM 30米毫米望远镜。 mm=（0.91 ± 0.02）Jy. 3 mm线偏振度（p3 mm= [13.5 ± 0.3] %）和偏振角（χ3 mm= [37.3 ± 0.8] °，在赤道坐标系中表示）在我们观测的时间跨度内也是恒定的。虽然时间取样和信噪比较差，但我们对3C 286的1 mm观测也可以用1 mm通量密度的恒定源（S1）再现 mm= [0.30 ± 0.03] Jy），极化分数（p1 mm= [14.4 ± 1.8] %）和偏振角（χ1 结论这一点，再加上先前已知的3C 286的紧凑结构--在天空中延伸了~3.5“”--使我们能够提出3C 286作为一种新的校准器，用于3 mm波长的单碟和干涉偏振观测，并可能在更短的波长下进行观测。
ContextSeveral millimeter and submillimeter facilities with linear polarization observing capabilities have started operating during the last years. These facilities, as well as other previous millimeter telescopes and interferometers, require bright and stable linear polarization calibrators to calibrate new instruments and to monitor their instrumental polarization. The current limited number of adequate calibrators implies difficulties in the acquisition of these calibration observations.AimsLooking for additional linear polarization calibrators in the millimeter spectral range, we started monitoring 3C 286 in mid-2006. This source is a standard and highly stable polarization calibrator for radio observations.MethodsHere we present the 3 mm and 1 mm monitoring observations obtained between September 2006 and January 2012 with the XPOL polarimeter on the IRAM 30 m Millimeter Telescope.ResultsOur observations show that 3C 286 is a bright source of constant total flux with 3 mm flux densityS3 mm= (0.91 ± 0.02) Jy. The 3 mm linear polarization degree (p3 mm= [13.5 ± 0.3] %) and polarization angle (χ3 mm= [37.3 ± 0.8] °, expressed in the equatorial coordinate system) were also constant during the time span of our observations. Although with poorer time sampling and signal-to-noise ratio, our 1 mm observations of 3C 286 are also reproduced by a constant source of 1 mm flux density (S1 mm= [0.30 ± 0.03] Jy), polarization fraction (p1 mm= [14.4 ± 1.8] %), and polarization angle (χ1 mm= [33.1 ± 5.7] °).ConclusionsThis, together with the previously known compact structure of 3C 286 – extended by ~3.5′′ in the sky – allow us to propose 3C 286 as a new calibrator for both single-dish and interferometric polarization observations at 3 mm, and possibly at shorter wavelengths.
