Introduction

It is possible that NRAO has already been able to retrieve your sources from what you specified in your proposal. If this is the case you will find these in a source catalog, labeled with an editable legacy ID name, in the column at the left. However, you should follow the examples below to get a feel for what is in your source catalog. You will want to check the entries in your source catalog, especially the accuracy of positions and the velocity specifications of your target sources, and the examples will help you check and/or modify the content.

The icon menu between the source search tool and the source catalog list in the left hand side column was introduced in the previous chapter. Here the menu icons behave exactly the same as in the RCT. The fly-over help tool-tip will help remind you of their actions.

Also introduced in the previous chapter was the use of the options in the menu strip (e.g., FILE - CREATE NEW - CATALOG). The menu strip options in the SCT are slightly different, again with names that are quite self-explanatory about their actions in the table.

Below we will comment on each of the choices for Source Position(s), Source Velocity(ies), Source Image Link(s), and Source Brightness.
