Dear AIPS, do you know if AIPS 31DEC12 is working correctly within MAC Lion systems?
We are producing images in two sites, Mexico and Barcelona. In Barcelona we have Snow Leopard working with AIPS 31DEC11 producing images
with IMAGR without any problem. However in Mexico with Lion system and AIPS 31DEC12 we are obtaining images with completely different things. We know that the spectral channels we are managing
have strong signal (masers), and in fact we are mapping without any problem those images using Snow Leopard and AIPS 31DEC11 in our mac computer in Barcelona.
As an example, I give you what IMEAN obtains from the image produced in Lion (same input parameters) without seeing the signal:
1 5 03-JAN-2012 17:17:50 IMEAN Image= SCHANEPOCH1 .ICL001. 303 1 xywind= 1 1 8192 8192

1 5 03-JAN-2012 17:17:50 IMEAN mac-pro- 31DEC12 TST: Cpu= 3.4 Real= 6 IO= 512
However, in our computer in Barcelona with Snow Leopard 31DEC11 (and also PC Linux) we obtain correct things with the maser at 1.7 Jy level seen:

In both sites, AIPS was installed with binaries.
Thank you in advance for your help,
