Studies for Regular Programmes#

About#

This wiki page is a reference for regular programmes for which there is now an accepted study. The reason for the page is that the accepted study isn't always easy to find, so I wanted to make a list for Chief Observers' reference.

N.B.: This page is not a place to add studies that you would like to be regular programmes: it is for COs' reference only.

HOP 79#

Purpose: Central meridian and activity belts irradiance scan. Study to use: we finally settled on the large-FOV Study #305 (IUU_SLOT_616X512_Q85). Use this once per pointing.

XRT Synoptic repointings#

Purpose: XRT makes a series of full-disc images, which means Hinode repoints at disc centre twice a day. Study to use: we use this opportunity to make regular measurements of the sensitivity of the instrument, using the average quiet Sun as a "standard candle". On one occasion per day (no more) use the original study, SYNOP001. It's an X-band era study, though, so if you want to run another in the same day, use SYNOP005A. They're both very short.
