This document describes the general requirements concerning the complete Data Flow system for an instrument. It provides an instrument description information and sets the requirements for Phase I, Phase II, and additional tools like exposure time calculators, pipeline calibration and quality control. This document is prepared by the Instrument Scientist, jointly approved and released by the DMD and the IR. It details the following:
This section of the document describes the instrument observing modes and resulting data formats. Typical data rates for these observing modes are indicated. All observing modes and typical targets (astronomical and calibration) are identified to define Templates (instrument operation mode) and Observation Blocks.
The Templates, calibration Observation Blocks, and instrument standard settings to be processed in pipeline mode are listed. Maintenance procedures necessary to reproduce the standard settings are identified. Target acquisition templates are defined,
FITS keywords and structure of the data is defined for each instrument in conformity with DICB. In particular the information needed for pipeline reduction and quality control is listed in this section.
User requirements concerning Phase II preparation, ETC, general reduction recipes and pipeline reduction recipes are defined in this section including expected accuracies, execution time, and indication of the modeling and calibration methods.
Engineering calibrations (like wavelength vs. encoder position, etc..) and maintenance procedures required to guarantee the stability of the standard settings, in particular the ones supported by the pipeline, are defined with the required accuracies.
At this phase a plan concerning the cost of the project for this particular instrument is produced.
