Three types of workstations are envisioned at the EOF: the workstations of resident, and in some cases nonresident, PI teams (Instrumenter Workstation or IWS), the Project Scientists' workstation, and the Science Operations Coordinator's workstation.
The Science Operations Coordinator's workstation is an EOF-resident workstation for use by SOHO science operations personnel, under the direction of the Science Operations Coordinator. This workstation will be used to receive and display data used in planning (e.g. from ground-based observatories), to resolve conflicts in instrument operations so as to produce weekly science operations schedules, and maintain various databases (such as the key parameters) to be transmitted to DDF and ISTP CDHF.
The Project Scientists' workstation is an EOF-resident workstation specifically for the use of the Project Scientists, but can also be used as a temporary backup to the Science Operations Coordinator's workstation in the event of unavailability. A PI team that has made arrangements with the Project Scientists to implement IWS software on the Project Scientists' workstation will have a similar backup capability in case of IWS failure. Non-resident investigators will coordinate their operational commanding activities via one of the EOF resident workstations, normally the Science Operations Coordinator's workstation. Commands from remote sites are to be submitted in a format ready for verification and validation before they are relayed to the SMOCC. Software to perform such functions on the EOF-resident workstation is to be furnished by each PI team requiring this capability.
All EOF workstations will support agreed upon standard software (Motif or Motif-compatible implementations of the OpenLook toolkit, IDL, SQL) and formats (FITS) to facilitate the exchange of catalog, scientific, engineering, and planning data. The only exceptions can be specific platforms which are not capable of supporting a subset of the agreed standards (e.g. certain PC Unix implementations for which IDL is not available, but which can open Motif windows on other EOF systems with IDL).
Each EOF resident investigation team will provide a sufficient number of dedicated workstations to acquire incoming data, process and/or monitor those data as required, and prepare schedules and command sequences for submission to the SMOCC.
Each EOF workstation will provide its own capabilities for interfacing with the GSFC EOF Local Area Network (LAN), including provisions for any special additional data interfaces.
Each EOF workstation will provide its own capability for storage of instrument data and resident databases, and for data display and hardcopy, unless specifically stated otherwise herein or in the ECS FRD.
Each EOF workstation will provide its own capability to obtain data from a variety of databases, with elements on a common file server as well as on individual teams' workstations. The individual instrument databases should be accessible to other SOHO users at the EOF. Each PI team will develop and maintain a catalog of accessible files for that instrument. This catalog will also be readable through the EOF LAN interface.
Security provisions to ensure that command transmissions from remote sites over public networks do in fact originate with the authorized PI team and have been received intact are to be installed on the remote and EOF resident workstations.
All EOF workstations will be compatible with standard U.S. power (60 Hz, 110 V) and receptacles.
