This program is designed to verify acquisition parameters at LP6 and to produce spectra at several regions on the detector that would normally be used for target acquisition comma but for which data are not downlinked as part of the acquisition process. The idea is that if anything does go wrong with the acquisition tests we will have maps of the detector that we can then use for diagnostics. LP6 is at +6.5d_comma from the on-axis detector position comma The program uses ficticious offset targets to nod the telescope away from a centered target and then test the re-acquisition. Because these displacements need to happen along the AD and XD detector direction and target offset coordinates must be entered in RA and DEC comma the ORIENT angle for each visit must be restricted to +-- 0.5 degrees comma which also means a date range restriction. The date ranges and ORIENT restrictions for each visit are described in the program description. The program is modeled after the LP5 version of this programdoublePoint 16432. It uses the target WDG-1 (SK 191) and cenwave G160M-1577 for all exposures. Prior to the execution of this program all LP6 SIAF comma aperture mechnism positions comma TA subarray comma and foci must have been installed. There is no special commanding in this program. Please see special request at the bottom of the proposal description. Those requests still apply here.

本程序旨在验证LP6平台的采集参数，并在探测器的多个常规用于目标采集的区域生成光谱，但此类区域的数据并不会作为采集流程的一部分下行至地面。其设计初衷为：若采集测试出现异常，我们可获取探测器的映射图像以用于后续诊断分析。LP6相较于轴上探测器位置偏移+6.5°。本程序采用虚拟偏移目标，将望远镜从对准的目标位置小幅偏移，随后测试重新采集流程。由于偏移操作需沿探测器的AD与XD方向进行，且目标偏移坐标需以赤经（RA）与赤纬（DEC）格式输入，因此单次观测场次的定向角（ORIENT）需限制在±0.5°范围内，这同时要求对观测日期范围进行约束。单次观测场次的日期范围与定向角限制已在程序说明中详细载明。本程序基于该程序的LP5版本doublePoint 16432开发。所有观测曝光均使用目标WDG-1（SK 191）与中心波长配置G160M-1577。在本程序执行前，需完成所有LP6相关的科学仪器孔径文件（SIAF）、孔径机构位置设置、靶面采集子阵列（TA）以及焦面组件的安装调试。本程序无需特殊指令。请参阅提案描述底部的特殊要求，此类要求同样适用于本程序。
