The Process of Planning and Implementing SDSS-V projects in the era of robotic Focal Plane System (FPS)

The Sloan Digital Sky Survey has recently reached its fifth generation SDSS-V which consists of the projects Milky Way Mapper (MWM), Black Hole Mapper (BHM), and Local Volume Mapper (LVM). The main difference of this generation is the use of Fiber Positioner System (FPS).

The Process of Planning and Implementing SDSS-V projects in the era of robotic Focal Plane System (FPS)

The Sloan Digital Sky Survey has recently reached its fifth generation SDSS-V which consists of the projects Milky Way Mapper (MWM), Black Hole Mapper (BHM), and Local Volume Mapper (LVM). The main difference of this generation is the use of Fiber Positioner System (FPS). In this system each optical fiber is attached to a robotic positioner that determines the final position of the fiber in the focal plane. This system comes to replace the long used metal plug-plates whose fixed locations provided much less flexibility for observation. In this talk I will focus on the different stages of planning and implementing observations used for the MWM and BHM projects, that used the APOGEE and BOSS spectrographs. This process is maintained by a group of softwares that are constantly evolving and providing feedback to each other. First, robostrategy determines the targets and cadences used for each field observed, based on overall LST restrictions and lunation. Then, roboscheduler provides a schedule aimed to complete the observing strategy. Finally, obsersim provides a roboscheduler result based on realistic weather and observing conditions. I will provide a description of the interplay of these softwares, and a general overview of the stage of SDSS-V projects and opportunities for participation.
