Student Hera: Imaging Tool

Imaging Tool - Basic Functions

Student Hera will allow you to open different images that have been collected from the ROSAT satellite. The tools in Student 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 Student Hera.

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

To install the Hera software, please visit this page: Installing Student Hera on your computer.

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.
