D. Synoptic and Other Studies

syo20100504-01 => EIS Spectral Atlas Synoptic Programme#

  – Young (pyoung@ssd5.nrl.navy.mil), Warren, Mason, Del Zanna

-- run twice each month; in the first and third full weeks of the month
-- run PRY_slot_context_v3; Duration: 3min 29s; Data volume: 5 Mbit
-- follow with either Atlas_30s (34min, 257 Mbit), or Atlas_60s (65min, 257 Mbit)
-- pointing to be specified by email to CO at start of observing week by P. Young
-- in absence of specific target, CO is free to choose any solar feature on- or off-disc
--   *NOTE: use Atlas_30s only if an AR is forecast to produce M-class or greater flares; use Atlas_60s for all other targets*

syo20100713-02 => Full CCD Study to Measure Relative Wavelengths#

  – Warren (hwarren@nrl.navy.mil)

-- run HPW020_VEL_FULLs1 (ID # 413)
-- full CCD sit-and-stare study; Duration: 45 min; Data volume: 243 Mbits.

E. Test and Calibration Studies

test-01 => EIS slit calibration#

  – Young (pyoung@ssd5.nrl.navy.mil)

-- Obtain co-spatial data in the 1", 2" and 40" slits for various calibration tests (slit widths, tilt, intensity calibration)
-- run CALIB_slit_slot_v2 (ID # 389)
-- study includes three separate rasters; each must be individually pointed
-- point off-limb above the quiet Sun at the equator (either limb)
-- make two separate adjacent entries of calib_slit_slot_v2 on the timeline
-- select Solar-X position 50-60” above limb; same for each of the rasters in both study entries
-- select Y position with the YIP input rather than the solar-Y position
-- set the YIP entry to 511 for each of the three rasters in first study entry
-- for the second study entry, set YIP to 1 for each of the three rasters
-- data volume: 35 Mbits
-- duration: 56m.

test-02 => EIS velocity calibration#

  – Kamio (kamio@linmpi.mpg.de)

-- Determine the slit tilt and curvature in full Y height for velocity calibration
-- execute raster scans at three positions with 1" and 2" slits
-- run ID 375 SK_DEEP_5x512_SLIT1 - the 1" slit study, with Y initial positions
   #1 YIP=1; #2 YIP=256; #3 YIP=512
-- run ID 376 SK_DEEP_10x512_SLIT2 - the 2" slit study, with Y initial positions
   #4 YIP=1; #5 YIP=256; #6 YIP=512
-- six consecutive rasters require total time 60min and data volume 45Mbits
-- target: quiet region near disk center (0", 0"); shift EIS FOV ±200" in E-W direction to avoid ARs; do not run if ARs in target area;
-- keep the same mirror initial position (MIP) for all rasters.

test-03 => EIS Slot Deconvolution Test#

  – Sun (js2@mssl.ucl.ac.uk)

-- Develop method to deconvolve EIS slot data
-- Two studies:
   * js2_decon_slot_sc_LT (ID # 429): data volume: 3.71Mbits; duration: 1m51s
   * js2_decon_ref_vel_LT (ID # 430): data volume: 87.87Mbits; duration: 47m37s
-- Instructions for planner:
   - Run study (ID # 429) first, then consecutively run study (ID # 430), then run study (ID # 429) again.
   - It's prefer that the slot study (ID # 429) repeats a few times,
     eg. study429 (x6), study430 (x1), study429 (x6)
-- Target:
   - simple active region;
   - FoV to cover AR edge to detect outflows;
   - both rasters to have identical pointing
-- Run during SAA-free interval preferred
