HaloSat is a CubeSat-class microsatellite sensitive in the 0.4 to 7.0 keV energy band and designed to survey the entire sky in search of soft x-ray emissions from highly ionized oxygen residing in the halo of the Milky Way galaxy. Those observations will help constrain the mass and spatial distribution of the Milky Way halo and help us understand if hot galactic halos constitute a significant contribution to the overall cosmological baryon budget. We describe the science instrument calibration products, including channel-to-energy transformation, instrument energy resolution and instrument response, and the on-ground efforts that led to their creation. We also describe the alignment process used to obtain the field of view information for the HaloSat science instrument.

HaloSat科学仪器的地面校准

HaloSat是CubeSat级的微卫星，在0.4至7.0 keV的能带内敏感，旨在探测整个天空，以寻找银河系晕圈中高度电离的氧的软X射线发射。这些观测将有助于限制银河系光晕的质量和空间分布，并有助于我们了解热银河系光晕是否对整体宇宙重子预算有重大贡献。我们介绍了科学的仪器校准产品，包括通道到能量的转换，仪器的能量分辨率和仪器的响应，以及导致其创建的现场工作。我们还描述了用于获取HaloSat科学仪器的视场信息的对齐过程。
