Add the source information

Enter the information on your science target (or targets) in the Field Setup editor pane (see Fig. 3.2). If your source has an entry in SIMBAD or NED, you can simply type in its name in the Source Name field and resolve the coordinate and velocity information from there (see Fig. 3.2), instead of filling it in manually. Please be aware that it is your responsibility to ensure that this information is correct. Since the source coordinates and the velocity are used by the OT to calculate the pointing(s) and the sky frequencies respectively, it is vital that they are correct in the submitted proposal. Solar System targets can be selected from a pull-down list if the Choose a Solar System Object box is checked.

Next, specify the Target Type by selecting one of the radio buttons. A Science Goal may contain a total of 150 offset pointings attributed to one or more sources located within 10 degrees of each other on sky if Individual Pointing(s) is selected, or one Rectangular field mosaic, again encompassing up to 150 pointings (for details on defining the spatial setup for these two cases see Step 3.6). For Individual Pointing(s) you can add additional sources with the Add source button. You can also read in a target list from an ASCII file (see the Source Properties section in the User Manual for the required input format). Note that if several sources with different velocities are specified in one Science Goal up to 5 separate frequency tunings will be allowed (the OT will determine how large the frequency shift can be within a single tuning based on the width of the spectral windows and the lines as specified by the user). All of these tunings must fall within one ALMA band.

For each source, you are required to provide an estimate of the Peak Continuum and/or Peak Line Flux Density per Beam, Continuum and/or Line Polarisation Percentage and Line Width as appropriate for your Science Goal correlator setup. The peak flux density entered should be an estimate of the weakest component driving the sensitivity requirement of your Science Goal and be adjusted for the Bandwidth used for Sensitivity (see Step 3.8). For continuum observations the peak continuum flux density must be entered, while for spectral line and spectral scan observations it may be appropriate to enter both the peak flux of the weakest line to be observed and a continuum flux, as well as the smallest line width (FWHM) expected. The polarisation percentage is required only if full polarization observations are requested. The source parameters entered are used to report back a number of quantities in the Technical Justification editor (see Step 3.9) and the proposal/science goal summary sheets. They are designed to help users choose appropriate parameters in the Control and Performance parameters editor (Step 3.8) and are used for the technical assessment of the proposal.
