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, 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 up to 15 targets within 15 degrees of each other on sky, if Multiple Pointings is selected, but just one Rectangular field (for details on defining the spatial setup for these two cases see Step 3.6). For Multiple Pointings you can add additional sources with the Add source button. You can also read in a target list from an ASCII file (see the Adding Source information section in the User Manual for the required input format). Note that if several point sources with different velocities are specified in one Science Goal only 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 Line Flux Density per Beam, Polarisation Percentage and Line Width. The peak flux density entered should be an estimate of the expected flux appropriate for your source and setup (e.g. referring to the line you want to observe, or the continuum in the bandpass proposed). The polarisation and line width should only be entered if applicable to your scientific objective. These quantities are used primarily for the technical assessment of your proposal. Please make sure that the Control and Performance parameters entered in Step 3.8 are appropriate considering the estimated target properties.
