Hi Eric,<br><br>I wrote out a file from TASAV which exhibits the behaviour. You can get it at /users/adeller/forsnedt_uv.fits. I double checked by loading the FITS file back into AIPS, and the the first time I repeated the process it happily saved the table. I then tried again with SN version 5 instead of 6, and it crashed as before. The input/output from below is from when I ran SNEDT before writing the file out and reading it back in - the only difference is that I look an SN table 6 instead of 5.<br>
<br>In both cases, I paged through the first few antennas and set the display to delay and rate before exiting. I believe SN table 6 was generated by CALIB and SN table 5 was from FRING. Here are the inputs and output:<br>

Hi daip,<br>
<br>
It seems there is a bug that has been introduced into SNEDT sometime in the last couple of months. If I open an SN table to edit it, page through some antennas and change what is being displayed (i.e. put up delay and rate, for example) and then exit without making an edit, SNEDT crashes complaining about a row ****. See output below. <br>

This is running 31DEC10 which is MNJ'd every night. I don't have any other versions to test, but I had not seen this bug before a month or two ago. Initially I thought it was related to some external software I was using, but now I've seen I can reproduce the bug in AIPS directly (change displayed quantity, change antennas, exit without any edits).<br>

I cannot make it do this. It is clear that it rereads the table at the end but your messages suggest that the info in core is messed up before<br>
that happens and I cannot get it to do that with any of the trials<br>
I did. Is there some way you could do a TASAV and make a FITS file which I could read from somewhere? There aren't a lot of adverbs but it might help to know what they were also.<br><font color="#888888">
