If the predicted temperatures exceed the planning limits, adjustments are made such as turning off one or more optional CCDs, splitting an observation, or rescheduling an observation at a more favorable pitch angle.
The blue boxes represent the active chips and the yellow, dashed box represents the optional chip for the observation.
The program can be run with only an event file, with the aspect solution and mask file of the observation as optional parameters.
Problematic observations with Optional chips are thus less likely to be split into multiple pieces than they would be if all the chips are required.
The proposer should pay special attention to the pros and cons of designating optional CCDs for their HETGS observation, as opposed to simply requesting the entire ACIS-S chip set.
In addition, in the optional input interface, for "plot observations" was selected "no" and the "simulated time beyond observations" was set equal to 0.2, as we were interested in the dynamics of the model from time zero to 20% additional time beyond the timepoint of the latest observation (see Supplementary Figure S2).
Creating observation-specific gRMFs is optional, and is discussed further in the Loading the Instrument Responses section.
The protocol has several optional extensions, one of them being, resource observation.
Choosing Optional CCDs & Optional CCD Policy The observer may specify that a given CCD must be on for an observation by entering "Y" for that CCD at the appropriate place in the RPS form.
They were also asked about specific informal PD programs (e.g., mentoring, peer support, observations), and whether they were optional or mandatory.
