NMS Command Line Driven Programs 3.1 . A visit refers to a group of observations which should be scheduled contiguously on the mission timeline. The program uses an exposure time calculator which takes into account the background light from zodiacal dust, the OTA and sunshield self emission, and the instruments. The schedulability of the visits are also restricted by sun and moon avoidance constraints. The highest score for a particular observation occurs when it schedules most efficiently.
Preference is given to observations with high scores.
A maximum visit duration can be specified on the command line. The final schedule is then displayed to the output report file, along with the list of failed candidates. An instrument level summary is also provided. Report modes can be specified to control the level of detail written to the output file. This causes the program to recalculate exposure times and perform scheduling for each set of input parameters being specified by the user.
