An HouseKeeping (HK) time profile is like a normal
only the quantity present as a function of time are not counts taken
from a science data file, but is the value of an
(voltage, temperature, setting ...).
These accumulations are similar to normal accumulations,
one main difference being that one shall select a
for the wished HK parameter, and this often automatically selects the telemetry
packet to use.
As for normal accumulations as prerequisites one shall ensure that
There is no way nor sense in using a quantity different from TIME or
to use the pseudo accumulation mode for HK time profiles, the environment
have no effect.
However the following environment variable can be used to control the
default behaviour. By default the digital values of the HK parameter in
telemetry are converted to engineering (or physical :-) ) units as
appropriate. This behaviour can be reversed if raw digital data are
wished. Toggle is possible using commands :
