The activity on EM follow-up requires using some software which is not compatible with the Virgo software environment.
For this reason, an alternate set of virtual machines should be used.

Virtual machines access

A set of 14 virtual machines is available:

vesf0.virgo.infn.it
vesf1.virgo.infn.it
...
vesf13.virgo.infn.it

Students are kindly asked to connect to the machine corresponding to their username, modulo 13.
For instance, user "school" will issue from Linux the command

 ssh -X school@vesf0.virgo.infn.it

user "school1" instead
 
  ssh -X school1@vesf1.virgo.infn.it

and so on, until

 ssh -X school14@vesf0.virgo.infn.it

Environment setup

 Beware that the home directory in the "vesf#" machines is not the same as the one on the "farmn#" machines!

 To set up the environment, after logging in your vesf# machine, please issue the following three commands:

• cp ~vesfuser/.tcshrc .
• source .tcshrc
  
• cp -rf ~vesfuser/EM_Followup/EMTUTORIAL .

DS9 software setup

To set up funtools.ds9:

• ds9
  
• Edit->Preferences->Analysis-> Browse: /usr/share/funtools/funtools.ds9
• Save
• Reload ds9 and verify Analysis -> there is Funtools at the bottom
  

Exchanging information

 It is possible to read and write from the directory

    / opt/w3/VESF

 which corresponds to the web directory http://wwwcascina.virgo.infn.it/VESF
 protected with the usual username and password for the VESF.
 This area can be useful to make available and visible to others your work. Please create a directory of your own to avoid deleting stuff belonging to others!

 To copy from/to your alternate home directory in the farmn# machines, please use the scp command.
 As an example, being logged on a vesf# machine, you can copy a file "toto.dat" to your home in the farmn machine by the command

 scp toto.dat farmn1.virgo.infn.it:toto.dat
