%%warning The following section %%(color:#5555ff;)in blue%% was written prior to Hinode changing from X-band to S-band telemetry. Therefore, please bear in mind that these studies are unlikely to be able to run at this time.

However, the discussion of the scientific __type__ of observation is still valid, and many new studies have been designed to have a lower volume for the new telemetry situation. For example, {{PRY_footpoints_v2}} has been succeeded by {{PRY_footpoints_lite}}. See [Study4LowDataVolume] for some more examples of lower-volume studies, though.

%%(color:#5555ff;)This is a list of some studies that I've either designed or used that I think are generally useful.


Consists of two rasters, the first being a 40" slot context raster (600"x512" field of view). The narrow slit raster has a moderate cadence (23mins), wide range of emission lines, 100x240 arcsec^2 field of view. Uses 2" slit.


Similar to above, but more focussed on hot plasma, and uses 1" slit. Also has a 40" slot context raster. 


This is a large field of view (460"x384"), 1" slit raster suitable for diagnostic and velocity maps of ARs. The duration is 5hr 40mins and so fits in the inter-synoptic slots nicely.


A high cadence (4mins) raster covering 40x120 arcsec%%sup 2%% with many diagnostic lines, and a 10s exposure time. It is a good diagnostic study for studying flaring activity in active regions. 

!! Eclipse season

During the eclipse season, it is possible to run studies with a higher data rate than normal during the day period, leaving the night periods empty on the timeline. Some studies that are suitable for running in this way are:


Takes full CCD spectra over a 128x128 arcsec^2 area, with 25s exposure times, and 1" slit. Duration: 1 hour. Data rate: 96 kbits/s.


Takes over 60% of the EIS spectral bands (mainly dropping low sensitivity areas), and covers 105x178 arcsec^2 area, with 40s exposures, and 1" slit. Duration: 1hr 22mins. Data rate: 50 kbits/s. Includes a slot context raster.
