Creating and transferring non-sidereal files

This page describes the traditional way of creating and transferring non-sidereal files. Please also refer to the easier and simplified procedure.

Transferring tracking files

Tracking files has to be copied to a computer called TSC, usually through a computer called g2stat, before starting tracking.

First, copy the file from your computer to g2stat (g2stat.sum.subaru.nao.ac.jp) as the user kansoku. You can copy the file from ANA using the procedure below when the file has been created on ANA as shown below. Use an FTP or SCP client on your computer. Below is an example using a Unix-like OS.

$ scp sample.dat kansoku@g2stat.sum.subaru.nao.ac.jp:
kansoku@g2stat.sum.subaru.nao.ac.jp's password: Please ask an operator for password
sample.dat                                    100%  566     0.6KB/s   00:00    

Second, copy the file to TSC logging into g2stat. Use an SSH client or terminal emulator on your computer.

$ ssh kansoku@g2stat.sum.subaru.nao.ac.jp
kansoku@g2stat.sum.subaru.nao.ac.jp's password: Please ask an operator for password
kansoku@g2s4:~$ scp sample.dat naoj@tsc:/JNLT/DATA/TSC/USER/MTDR/EXEC/UG8/
sample.dat           100% |*****************************|   566       00:00    

Now the telescope should be able to track your non-sidereal target from the Observation Control System. Please ask the support scientist to execute a command like

SETUPFIELD OBE_ID=MOIRCS OBE_MODE=IMAG OBJECT=sample RA=185406 DEC=-303521 INSROT_PA=0.0 EQUINOX=2000 COORD=FILE Target="08 sample.dat"

from the IntegGUI.

Creating tracking files

There are tools to create tracking files from orbital parameters for comets, large planets and moon, asteroids, and non-orbital objects. Please also have a look at format of the files.

Comets

Use an SSH client or terminal emulator on your computer to login as the user as your o-account to sumda.sum.subaru.nao.ac.jp and follow an example session below.

$ ssh o15XXX@sumda.sum.subaru.nao.ac.jp
