The casacore Measures messages about Leap seconds etc are just telling you that one of your files in /opt/data (I think ephemerides) is not up-to-date with respect to the the date of observation in the measurement set you are working with. But that should not be causing the crash. The Measures errors are just warning messages.
This web page (http://casa.nrao.edu/docs/userman/UserManse82.html) has instructions how to update the 'data' files.

So which observatory has generated your data?

I don't quite understand what you mean.My data has not yet been generated. The following error:

Is my target file sun0922. ms right? Or for other reasons?
How can you be running an imager without having data to image?

I would assume that mt-imager is trying to process your data file sun0922_ms. Unfortunately its crashing. Only the developer/programmer working on mt-imager can help you further.

..and here I am....
The last error is stating that he cannot find the observatory(telescope) in the Observatory table... Make sure you have the latest observatory table... (sometimes MeerKat and LOFAR are missing).
For the other error related to CUDA I suspect that you are not using architecture 3+ CUDA devices ie (K10,K20,K40 GTX6 series and GTX 7 series)
xiaoluo1314 if you wish we can set up a meeting, such that I can help you get over your problems.
Regards Daniel

hi Daniel,
thank you very much .I appreciate your,For me, I can't write, also can't think of such a good program. I am very willing to learn like you.So I hope you can give me a platform for the exchange of learning with you.I know you are very busy, I also don't want to disturb you.
Only hope you have time to help me see I put those unsolved problems,So I will be very grateful.So I will be very grateful.To say thanks again.
sincerely xiaoluo1314
Hi,thanks again.I think it a lot . 1.Here I have a question about where to set the arguments of observatory table.You see, in the comand of casapy, input tb.browse,then we input our height,lattitude,longtitude. 2.Then ,I wonder to know the ms file is generated by casa or this program itself. Thanks very much.
Its not clear to me what you are trying to do.
1) Are you trying to add latitude, longitude and height for an Observatory that is not in the geodetic/Observatories data file? If so which observatory? If you want to add a new observatory you need to have a working 'pyrap'. Well, you could also do it with casacore C++ code, but that would give me a real headache!
2) Measurement sets are either created a) by an Observatory doing an actual observation or b) by some program which can simulate an observation. CASA, for example, has a simulator tool which will allow you to create simulated ALMA observations / measurement sets.

It will be a pleasure helping you... Please communicate with me over support@mtimager.com such that we can set up a meeting and help each other.
