Hi everyone!I'm very new to IRAF and am attempting to use it to extract some velocity dispersions from some spectra I've been given. To do this, I am using the FXCOR task, but unfortunately when I enter the files I want to cross-correlate, I receive the following error:[code:1:1d59c59134]ERROR: FXF: EOF encountered while reading FITS file (name).[/code:1:1d59c59134]This only seems to happen to a couple of files -- unfortunately, they are my template spectra, and so are quite important! Are there any workarounds for this error?Thanks in advance!

The message sometimes means the FITS file was truncated, i.e. the padding NULL chars were lost in transfer. You should check the file size to be sure it is an integral number of 2880-byte blocks. It it does appear truncated, you can use the host 'dd' command to pad it again,. e.g.[code:1:35cd4192a5]
% dd if=temp.fits of=newtemp.fits bs=2880 conv=sync
[/code:1:35cd4192a5]The file might be corrupted in other ways as well, if you still have problems you can put it in ftp://iraf.noao.edu/pub and I'll have a look.-Mike

Hi Mike,I checked the file sizes and they were, in fact, corrupted (they were all 0 bytes!). I've now downloaded them once again, and the problem seems to be fixed.Thank you very much!
