摘要

4[公式:见正文]m国际液镜望远镜(ILMT)是ARIES Devasthal天文台(印度北阿坎德邦)的一个指向天顶的光学观测设施。ILMT的第一次灯光准备活动于2022年4月完成,随后于2022年5月初进行了天空测试。该望远镜将利用时间延迟积分技术对天空的窄带([公式:见正文])进行多波段光学成像(SDSS[公式:参见正文]、[公式:请见正文]和[公式:详见正文])。单次扫描ILMT图像的积分时间为102[公式:见正文],可以共同添加连续的夜间图像,以进一步提高信噪比。图像相减技术也将应用于夜间记录的观测,以检测瞬态,即通量或位置变化的物体。目前,该设施正处于调试阶段,将于2023年3月开始正常运行。本文讨论了初亮前的主要准备活动,以及获得的初步结果。

First Light Preparations of the 4m ILMT
The 4[Formula: see text]m International Liquid Mirror Telescope (ILMT) is a zenith-pointing optical observing facility at ARIES Devasthal observatory (Uttarakhand, India). The first light preparatory activities of the ILMT were accomplished in April 2022 followed by on-sky tests that were carried out at the beginning of May 2022. This telescope will perform a multi-band optical (SDSS [Formula: see text], [Formula: see text] and [Formula: see text]) imaging of a narrow strip ([Formula: see text]) of sky utilizing the time-delayed integration technique. Single-scan ILMT images have an integration time of 102[Formula: see text]s and consecutive-night images can be co-added to further improve the signal-to-noise ratio. An image subtraction technique will also be applied to the nightly recorded observations in order to detect transients, objects exhibiting variations in flux or position. Presently, the facility is in the commissioning phase and regular operation will commence in March 2023. This paper presents a discussion of the main preparation activities before first light, along with preliminary results obtained.

期刊介绍: The Journal of Astronomical Instrumentation (JAI) publishes papers describing instruments and components being proposed, developed, under construction and in use. JAI also publishes papers that describe facility operations, lessons learned in design, construction, and operation, algorithms and their implementations, and techniques, including calibration, that are fundamental elements of instrumentation. The journal focuses on astronomical instrumentation topics in all wavebands (Radio to Gamma-Ray) and includes the disciplines of Heliophysics, Space Weather, Lunar and Planetary Science, Exoplanet Exploration, and Astroparticle Observation (cosmic rays, cosmic neutrinos, etc.). Concepts, designs, components, algorithms, integrated systems, operations, data archiving techniques and lessons learned applicable but not limited to the following platforms are pertinent to this journal. Example topics are listed below each platform, and it is recognized that many of these topics are relevant to multiple platforms. Relevant platforms include: Ground-based observatories[...] Stratospheric aircraft[...] Balloons and suborbital rockets[...] Space-based observatories and systems[...] Landers and rovers, and other planetary-based instrument concepts[...]
