[daip] FRING memory requirements

[Ingyin Zaw]

Hello,

I'm trying to run FRING with aparm(5)=2 to solve for multiband and single 
band delays on a file with 256 channels and 8 IFs (experiment BK114A). I 
get the following error.

FRING1: Task FRING  (release of 31DEC09) begins
FRING1: You are using a non-standard program
FRING1: Doing no flagging this time
FRING1: Selecting the data
FRING1: Dividing data by source flux densities

AIPS 1: Resumes
AIPS 1: RETURN CODE      2 RECEIVED: STOPPING

I have set dparm 3 1 1 4.1 0. It seems strange that it fails for such a 
small search window. It fails even when the search window is set to 0.1 
nsec and 0.1 mHz. I'm not applying any calibrations or bandpass.

I'm running 31 DEC 09, 64 bit AIPS on a machine with following 
specifications:
Linux rglinux9.cfa.harvard.edu 2.6.18-128.1.1.el5 #1 SMP 
Mon Jan 26 13:58:24 EST 2009 x86_64 x86_64 x86_64 GNU/Linux

I have seen the same problem on 31 DEC 09, 32 bit AIPS as well on an 
experiment with 512 channels and 8 IFs (BB242D).

I have made a FITS file of only the source I used for FRING for testing. 
It's available by ftp from cfa-ftp.harvard.edu,
User = anonymous, password = <youremailaddress>.
The file is located at: incoming/lincoln/BK114A_2145.FITS

Please let me know what I can do to be able to run FRING with aparm(5)=2.

Thank you,
Ingyin
