Frequently asked questions

Using the telescope

Q:

Is it possible to operate the telescopes from Windows?

A:

Yes, if you have an X server such as VcXsrv. Alternatively, you may be able to use the Windows Subsystem for Linux; recent versions have built-in graphical user interface support and no longer require a separate X server.

Data

Q:

What is the local standard of rest (LSR)?

A:

The motion of the sun relative to a hypothetical circular orbit about the centre of the galaxy. The local standard of rest is approximately 16.5 km/s in the direction of the galactic coordinates l = 53°, b = 23°.

Q:

Are the velocities given from DRP relative to the LSR?

A:

Yes, the speed in respect to the LSR in the observed direction is calculated by qradio and stored in the fits header under the keyword VLSR. This information is then read by DRP
