Abstract

The first pictures of the nucleus of Comet Halley were returned from the CCD TV system (TVS) placed onboard the two Soviet spacecraft Vega 1 and 2. Comet Halley was observed from 4 to 11 Mar. 1986, and ~1500 images were transmitted to the earth. The raw data are given in digital numbers which must be converted into units of brightness. After a brief description of the experiment, the on-ground calibration tests are discussed. Many images were registered and processed to obtain standard correcting images and absolute calibration. Photometric performance could also be checked during flight with observations of Jupiter; in-flight and on-ground performances are compared.

摘要

第一张哈雷彗星核的照片是由搭载在苏联两艘“韦加1号”和“韦加2号”航天器上的电荷耦合器件电视系统（TVS）传回的。1986年3月4日至11日对哈雷彗星进行了观测，并向地球传输了约1500张图像。原始数据以数字形式给出，必须将其转换为亮度单位。在对实验进行简要描述之后，讨论了地面校准测试。记录并处理了许多图像以获得标准校正图像和绝对校准。还可以在飞行过程中通过对木星的观测来检查光度性能；对飞行中和地面的性能进行了比较。
