4.1.3 Process Doc No. SALT1700AS0001 Issue A TCS Specification The work flow for an observation is described in the SALT Operational Requirements document. The paragraphs below indicate the information, displays, controls and software tools that the TCS must make available to support each phase of an observation. The phases are: Phase 1: PI initial preparation prior to TAC approval Phase 2: PI final preparation after TAC approval Phase 3: Observation of object by SALT Phase 4: Data retrieval and data reduction by PI 4.1.3.1 PHASES ONE AND TWO The tools required by the PI and/or the Co-investigator are similar to those used by HET (see http://rhea.as.utexas.edu/HET_software.html). Details are TBD2. 4.1.3.2 PHASE THREE The TCS shall simplify the operation of the telescope by normally only displaying the information and control functions that are relevant in a particular state or phase of operation on the SO and SA workstations. This information is configurable (see section 5.3.1.2). Table 2 shows the seven major groups into which the controls and displays can be combined. Process Steps # SO Task Name SA Task Name 1,2,33 Day-time operations Observation planning, data archiving 3-9 Twilight Preparation Instrument set-up and calibration 10-15 Telescope Calibrations 16-19 Object Acquisition Object Acquisition 20-25 Object Setting Object Setting 26-29 Observation Observation 31,32 Dawn close-out Instrument calibration 4.1.3.3 PHASE FOUR Table 2: TCS Work Flow A data decompression tool will be made available to the PI to decompress data, when data compression has been implemented. Some preliminary data analysis may be performed by the SA, but he will use tools described under Phase 3. 17
