Imaging Tool - Basic Functions

Hera will allow you to open different images that have been collected from the ROSAT satellite. The tools in Hera will allow you to manipulate the images in different manners to look for new information. Follow the instructions below to get a guided tour of how to use Hera.

These directions can also be downloaded as a PDF file in the "PDF Files" menu tab.

IMPORTANT: For the image files being used, the only available tool that will produce anything is the POW Plot Tool. Do not use any of the File Utilities or XRONOS Tools; they are for another type of activity.
