EIS Master Study Database

Updating the MHC heaters study (default_heaters)

The MHC heaters are set to the Eclipse setting every May, usually around the 5th. They are reset to the Post Eclipse setting every September, usually on the 30th. The master database with the updated heaters settings needs to be made available to the planners at ISAS at least a week before it is uploaded in the plan.

There are 2 studies which control the MHC heaters settings; default_htrs1_6 and default_htrs7_12 .

Details for the studies are summarised in the following table:

Default heater studies
Database Id default_htrs1_6 default_htrs7_12
Master Database Id 000143 000144
PM Database Id 000101 000102

These 2 studies are used for both the Eclipse and Post Eclipse settings.

The procedure to update the MHC heaters is split into two parts; the first updates study default_htrs1_6 and the second updates study default_htrs7_12.
