It is used on two pages [2,3], with slightly different captions: * Keith Dancey using ECSTASY on a Sun 3/50 workstation, 1989 [1] * Fig 2.4 ECSTASY in use on a Sun 3/50 workstation. (89RC5954) [2] The ECSTASY page says [2]: ECSTASY (Environment for Control System Theory, Analysis and SYnthesis) was funded by SERC's Control and Instrumentation Sub-Committee via the Computing and Design Techniques for Control Engineering (CDTCE) Management Committee. ECSTASY had two aims: to provide a common interface to well established packages in the area, such as ACSL and ProMatLab and to provide a system in which new control algorithms could be developed. The common front end approach meant that control engineers would not have to learn a new interface to use a new package while a common environment for new developments meant that the results of such developments could be easily transferred to other researchers and to industry. In 1986, a survey of available control systems developed by academic groups and commercial offerings was undertaken. The conclusion was that none met the requirements although many had features that were needed in a control environment. The decision was made to write the new environment in C with the target being either SUN-3 workstations or VAX systems. An early version of ECSTASY was released to sites in 1988. The basic environment was developed at UMIST's Control Systems Centre with a block diagram editor provided by University College, Swansea. RAL's role was to provide management and technical support, and test the system. RAL also interfaced the TSIM simulation package to ECSTASY. RAL organised two rounds of beta testing. The second beta test took place in 1989 . This was a 3 month evaluation by 4 academic institutions in collaboration with some industrial partners. The main people involved at RAL were Damian Mac Randall and Keith Dancey. The licensing terms for photos in the galleries are [4]: This Gallery currently contains over 3000 photographs that relate to Computing and computer staff on the Chilton site that housed both the Atlas Computer Laboratory and the Rutherford Appleton Laboratory. We would be pleased to receive copies of any other relevant photographs that people have. We welcome re-use of this material provided suitable acknowledgement is given to the Rutherford Appleton Laboratory and the Science and Technology Facilities Council (STFC). A link to and mention of: http://www.chilton-computing.org.uk/ would be appreciated. The photographs in this archive currently fall into three main classes: * Photographs taken by Harwell's Photographics Section (Harwell) * Photographs taken by Rutherford's Photographics Section (1965-2003) * Photographs from other sources (Other) Links to the sections are available in the header bar with the Rutherford set broken down into sections by date. The Keith Dancey photograph is not under gallery/ though, so it's not clear if it falls under the same permissive license. The Informatics Department falls under the Rutherford Appleton Laboratory (RAL) [5], which is explicitly listed in the license text. The Chilton page is hosted by the Science and Technology Facilities Council (STFC) [4,5,6]. In the United States, works produced by the government are in the public domain [7], but the UK has a Crown copyright [8]. They work around this by releasing many works under the Open Government License [9], but there is not explicit copyright or licensing information on either of the two pages showing this image [2,3].
