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
.
The study id's in the master database are 000143 for
default_htrs1_6
and 000144 for
default_htrs7_12
.
The study id's in the pm (test) database are 000101 for
default_htrs1_6
and 000102 for
default_htrs7_12
.
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.The cycling of the heaters for both settings can be seen here.
The heaters schedule can be seen here.
This procedure is used to update both the eclipse and post_eclipse settings. In steps 2 and 4 of this procedure use whichever instruction is appropriate.
That's it, all finished!
