For Cycle 18, we have implemented the following changes to APT for preparing Proposals:
- Hubble Legacy Archive - The HLA footprint service has been added to the Aladin tool in APT. Select File>Open in Aladin and then choose the HLA from the left hand column of Image Servers. See the HLA in Aladin documentation or training movie for details.
- Increased Scheduling Flexibility - If you find your observation is unschedulable due to critical scheduling constraints, there is now an option in Phase I which will increase the schedulability of your observations at the cost of orbital visibility. See the Orbital Viewing and Schedulability web page for details.
- Beta Phase II Mosaic tool - There is a beta capability for building mosaics in Phase II proposals that you may want to try. It allows you more control than the Phase I Mosaic tool. (If you are working on a mosaic larger than 16 tiles, save and restart APT if you have to change the size of the mosaic.) See the demonstration movie for more information.
- Larger Memory Option - For all platforms except Windows, APT now offers a larger Java memory footprint option. If you have more than 2 GB of memory this will allow you to use more of your available memory for APT (the new largest memory option is twice as much as the old largest memory option).
- Differencing Tool - Although it is not a new capability, most people were unaware of the tool in APT which can highlight differences between two proposals (or portions of one proposal). There is now a training movie about the Differencing Tool available.
- Context Sensitive Menus - APT now has context sensitive editing menus in the Tree Editor. For instance you can right click on a target to find options like "New Fixed Target" and "Delete" (instead of looking for these options in the menus or remembering the shortcuts/hotkeys).
- Native Mac Save & Load File Dialog - Mac users will now notice that when saving and loading files in APT, the native Mac save & load file dialog box is used instead of the generic java dialog box.
