Abstract

has developed an 800 m single-baseline interferometer consisting of 32 m (IR) and 16 m (IB) radio telescopes with 15 arcseconds of angular resolution. Irbene radio telescopes are operating at C/M/X-band (4.5-8.8 GHz). Raw telescope data are correlated with the Software FX Correlator (SFXC) [1] and output visibilities are calibrated with a ParselTongue ∗ pipeline. Data techniques provide a velocity resolution of 0.088 𝑘𝑚𝑠 − 1 and spectral resolution of 0.002 MHz and enabling observations to approach the theoretical sensitivity limit of the interferometer, at about 6 mJy for a 120 s integration. We propose to use the Irbene interferometer for discoveries in a new age of transient astrophysics. In this paper, we will show correlation and calibration schema and initial monitoring results.
用于mJy观测的单基线干涉仪
研制了一种800米单基线干涉仪,由32米(IR)和16米(IB)射电望远镜组成,角分辨率为15弧秒。Irbene射电望远镜工作在C/M/ x波段(4.5-8.8 GHz)。原始望远镜数据与软件FX相关器(SFXC)相关[1],输出可见性使用ParselTongue∗管道进行校准。数据技术提供的速度分辨率为0.088𝑘𝑚𝑠−1,光谱分辨率为0.002 MHz,使观测结果接近干涉仪的理论灵敏度极限,在120 s的积分下约为6 mJy。我们建议使用Irbene干涉仪来发现瞬态天体物理学的新时代。在本文中,我们将展示相关和校准方案以及初步监测结果。
