[daip] FRING

[Shen Zhiqiang]

Hi,

In running FRING, I saw many pieces of message as below

FRING      Time=   0/ 20 58  4, Polarization =   2
FRING     B= 01 - 04 IF=  1 R=     -22.5 D=      -5.9 SNR=  15.5
FRING     B= 03 - 04 IF=  1 R=     -21.5 D=     -19.5 SNR=  10.4
FRING     B= 04 - 07 IF=  1 R=     -22.5 D=     -16.6 SNR=171.1
FRING     B= 04 - 08 IF=  1 R=     -22.5 D=     -16.6 SNR=  10.6
FRING     FIT DID NOT CONVERGE FOR IF    1
FRING      This probably means that the starting value for the
FRING      delay or rate for one or more antennae is bad.  You
FRING      may want to set search windows and try again.

Obviously, this would lose some good detections. Is there any
way to avoid this? What does it mean to set search windows?
Are the windows used too small? 

Again, this happened many times in a single run of FRING. 
 
Best regards,
Zhiqiang Shen
