MIRI Anneal Template Parameters
JWST's MIRI Anneal Engineering template, available in the Astronomer’s Proposal Tool (APT), is used for calibration observations for the MIRI instrument.
Introduction
Purple text indicates the parameter is Limited Access.
Boldface italics type indicates the name of an APT parameter or a value for a parameter.
Red text indicates restrictions on a parameter.
Black text indicates an important note.
Brown text indicates notes for the developers.
Green text indicates the name of the parameter used by Commanding.
Items in brackets - <value> - are required values.
Items in square brackets - [<value>] - are optional.
This parameter is required to obtain Anneal observations. Note that this type of observation COULD (if proven) be obtained as a parallel to normal science observations. Detector anneals will be performed to treat cosmic ray damage. During the anneals, the specified MIRI detector will be heated up to ~15-20K above its nominal operating temperature and MIRI will not be usable
MIRI Anneal operations are expected (but not required) to be done in parallel with a slew (see Parallel and No Parallel Special Requirement Rules).
When used with both a PARALLEL and a SEQUENCE OBSERVATIONS [NON-INTERRUPTIBLE] special requirement, the next observation in the sequence may not be a MIRI observation.
The MIRI Anneal Engineering template consists of the following parameters:
| Field | Details | Values | Notes |
|---|---|---|---|
| General Information | |||
| Observation Number | assign observation number | number | |
| Observation Label | provide observation label | test | optional |
| Observations Comments | provide observation comments | test | optional |
| Special Requirements | specify special requirements | choose from list | if needed |
| Template Specific Information | |||
| Detector | select detector | choose from list | |
General Information
The following parameters are generic to all templates, and are not discussed in this article: Observation Number, Observation Label, Observations Comments , and Special Requirements.
Detector
DETECTOR [DETECTOR] = IMAGER, MRSLONG, MRSSHORT, MRS, ALL
This parameter specifies the detector that is to be used.
