Observation Proposals

• See details in http//solar-b.nao.ac.jp/operation_
  e/proposal_e.shtml
• To broaden community involvement in the Hinode
  mission the science team is offering the
  opportunity to participate in the definition and
  development of the observing program. This can
  take the form of either collaborative
  investigations with other ground or space based
  observatories or a request for a set of
  observational sequences to meet a specific
  scientific objective formulated by the requestor.
  To facilitate this program the Hinode team has
  created a group of seven Scientific Schedule
  Coordinators (SSCs) to both review requests and
  assist requestors in preparing their plans. It is
  the policy of the Hinode Science Working Group
  that all observing requests that are consistent
  with the objectives of Hinode will be accepted.
  However it is strongly recommended that
  individuals discuss their proposed observations
  with one of the SSCs before preparing and
  formally submitting their request to ensure that
  their proposed observations are not already part
  of the core team's program. Please note that
  having your observation program selected and
  implemented does NOT entitle you to exclusive use
  of the data. The Hinode open data policy applies
  to all data. Where the observation program
  involves more than one instrument, the requestor
  should contact an SSC associated with his primary
  instrument.
• 55 Hinode Operation Plans (HOP) have been
  proposed.

Planning Constraints

• Nominal allocation of telemetry for EIS is 50
  kbps. A study with higher data rate cannot run
  for a long time.
• The 24 hour planning period begins around 11 UT
• Hinode daily planning meetings occur at 0130 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 lt 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

For A New EIS Observation

• See details in http//solar.bnsc.rl.ac.uk/young/s
  olarb_eis/eis_study_guide.html
• A sequence of observation is called Study in
  the EIS plan.
• A Study consists of Rasters.
• A Raster contains a Line List.
• Line Lists, Rasters, and Studies are created by
  users using software, EIS Planning Tool, in SSW
  (solar software).

Flow of EIS Observations

• Prepare a Study using SSW by proposers.
• A Study file in the text format is sent to MSSL.
• e-mail to Khalid Al-Janabi
  kfj_at_mssl.ucl.ac.uk
• The Study is verified by the EIS proto-models at
  MSSL.
• The Study is registered in the EIS official
  database in SSW.
• The Study is set in a daily plan by EIS chief
  observers at ISAS.
• EIS in orbit observes the sun according to the
  Study description.

  have been registered in the official database.
• IDLgt eis_mk_raster
• Create Studies
• Can select Rasters that have been registered in
  the official database.
• IDLgt eis_mk_study
• Create Daily Plan at ISAS by EIS CO
