I have a 4 K image . This is Orion in the A array at 8 GHz.
the beam is 0.3 by 0.2 arc sec. The header is

AIPS 1: Minimum= -0.3204 Maximum= 12.9326 MilliJY/BEAM

I run TVAL or TVLO and it is happy for TYIN 1 TXINC 1 or
4 , or 8 . For TYIN 8 I can view the entire image.
But for TYIN 2 TXIN 2 I get the following
>typ tyin
AIPS 1: 2
>typ txin
AIPS 1: 2
>tvlo
AIPS 1: YIMGIO: OP,CHAN,NPIX,X,Y,ANGL ERROR: WRIT 1 1390 1 951 0
AIPS 1: TVLOAD: MDISK TV I/O ERROR = 2
AIPS 1: TV PROBLEM

An image is loaded however.
and for TYIN 4 etc here are the results :
>tyin 4
>txin 4
>tvlo
ie no error.
Thanks
