The Standard Hera Interface
Connecting to Hera
Once fv has been installed there are several ways to connect to Hera. The simplest method is to start the fv application, then select the "Connect to Hera..." option on the fv desktop manager window (it usually appears in the upper left corner of your monitor).
You may also connect to Hera directly without explicitly starting up the fv task.
Login ProcedureWhen Hera starts up, a new window should briefly appear stating "Trying to log on to available network" as it establishes communications with the Hera servers at the HEASARC. This window is usually only displayed for a few seconds before the next login window appears. If the window remains open for a longer period, then there may be difficulties with the network connections. In some cases, the firewall on the local machine may need to be configured to allow fv to communicate with Hera.
After a connection with the Hera server machine has been established, the following Login window will appear:
The functions on this window should be self evident: if you already have a Hera User Id and Password, then enter them in the entry boxes on the left, otherwise create a new one by enter the desired new user ID on the right (Hera will tell you if it is already taken). When creating a new user ID, you will be asked to enter your name and an email address which will only be used to contact you if there is a problem related to your account. Make sure that the email address is valid, otherwise your account, and any data in it, may be deleted without notice..
Main Hera WindowAfter logging in, the main Hera graphical user interface (GUI) window will appear:
The window on your machine may not appear exactly has shown here due to ongoing improvements to the interface. The main features of this window are:
Some of the other main features of the Hera GUI are described on the Frequently Asked Questions page.
Getting More Data to AnalyzeIf you have just created a new Hera User ID, there will of course be no data in it, except for a couple small sample files. To add more data sets from the HEASARC data archive to your Hera account, see the "Copying data to Hera" help page.
The main Hera GUI also lets you directly copy FITS data files between your local computer disk and your disk area on the Hera server. To do this, locate the name of the file in the remote or local directory listings on the main Hera GUI window, then drag (while holding down the RIGHT mouse button) the file name into the desired subdirectory in the other directory window. Only FITS files and small text files are allowed to be copied using this method.
