AI总结：
本文利用对耀变体3C 273的多台站准同时光谱观测，估计了亚利桑那大学SPOL光谱偏振仪各狭缝宽度的设备致宽，发现不同孔径间存在显著差异，强调了逐孔径校正的必要性。
摘要：
费米伽马射线太空望远镜的地基观测支持项目由亚利桑那大学利用Steward Observatory（SO）运营的2.3米Bok望远镜和1.54米Kuiper望远镜开展。该项目通过光谱观测（以及其他观测手段）监测耀变体源。然而，光谱观测中使用的不同狭缝宽度（范围从2.0到12.7角秒）所对应的设备致宽目前尚不可用。利用SO、Guillermo Haro天体物理观测台（OAGH）和San Pedro Mártir国家天文台（OAN-SPM）对耀变体3C 273的准同时光谱观测，我们能够对其中两个狭缝宽度的设备轮廓进行估计。由于设备致宽与狭缝宽度成正比，我们得以估计SO使用的全部六种狭缝宽度的设备致宽。我们发现不同设备轮廓之间存在显著差异，这强调了针对每个孔径校正设备致宽的必要性。
英文摘要：
The Ground-based Observational Support of the Fermi Gamma-ray Space Telescope is conducted by the University of Arizona using the 2.3m Bok and 1.54m Kuiper telescopes operated by the Steward Observatory (SO). This program monitors blazar sources with spectroscopic (among others) observations. Yet, the instrumental broadenings for the different slit widths used in the spectra, are unavailable (the widths range from 2.0 to 12.7 arcsec). Using quasi-simultaneous spectroscopic observations of the blazar 3C 273 between the SO, Observatorio Astrofísico Guillermo Haro (OAGH), and Observatorio Astronómico Nacional San Pedro Mártir (OAN-SPM), we can provide an estimation of the instrumental profile for two of the slit widths. Since the instrumental broadening and the slit width are directly proportional, we were able to estimate the instrumental broadening for all six slit widths used at the SO. We found significant variations between the instrumental profiles, emphasizing the need to correct the instrumental broadening for each aperture.
