Science operations with EIS Dr Peter Young Rutherford Appleton Laboratory, UK Dr Peter Young, Rutherford Appleton Laboratory
Rasters • The basic observation unit with EIS is a raster • Spectroscopy rasters • scan over an area with a narrow slit • performing a sit-and-stare with a narrow slit • Imaging rasters • scan over an area with a wide slit • performing a sit-and-stare with a wide slit Dr Peter Young, Rutherford Appleton Laboratory
Studies • A study comprises of one or more rasters • Example 1 • Raster 1: context images with the 40” slot • Raster 2: 50 exposures in sit-and-stare mode with 1” slit • Raster 3: context images with the 40” slot • Example 2 • Raster 1: large format context raster with 1” slit • Raster 2: 10 repeats of small format raster with 1” slit • Most studies actually comprise of only a single raster Dr Peter Young, Rutherford Appleton Laboratory
EIS planning • The study is the basic unit added to the EIS timeline Studies Dr Peter Young, Rutherford Appleton Laboratory
Planning constraints • The 24 hour planning period begins around 11 UT • Hinode daily planning meetings occur at 01:30 UT • 2-day weekend plans begin at around 11 UT Saturday • Hinode is re-pointed every ≈ 6 hours for the XRT synoptics • an EIS study should be < 6 hours in duration • Pointing information is needed for the daily meeting one day before the observations • small pointing adjustments are possible at the daily meeting on the observation day Dr Peter Young, Rutherford Appleton Laboratory
Study database • To browse the studies in the EIS database use: • Currently there are 226 studies in the database IDL> eis_xstudy Before you design a new EIS study, you must check that there is nothing similar already in the database! Dr Peter Young, Rutherford Appleton Laboratory
Scheduling EIS observations • 50 % of the Hinode observing time is allocated to Hinode Observing Programmes (HOPs) • The other 50 % is allocated to the core teams for each instrument • HOP proposals should be sent to a Science Schedule Coordinator (SSC) for one of the instruments • EIS: L. Culhane (MSSL), J. Mariska (NRL), T. Watanabe (NAOJ) Dr Peter Young, Rutherford Appleton Laboratory
