Some additional 'paranoia checks' added into the 4.75-4.77 applications identified an important bug in the central LALDemod() routine of the analysis code. (PoorBoy: your lost workunits were not in vain!). The maximum velocity of our detector (as the earth orbits the sun and rotates on its axis) is about 1% larger than the code allowed for, so for certain data sets and sky directions, a frequency array was one bin smaller than required. This has been fixed, and new applications (4.78, 4.79, 4.80) are now being distributed.

New applications are now available for Windows (4.75) Linux (4.76) and Mac (4.77). These should resolve the 'hanging workunit' problems described below

New applications are now available for Windows (4.75) Linux (4.76) and Mac (4.77). These should resolve the 'hanging workunit' problems described below. They also incorporate several other fixes and improvements. NOTE: if you start to experience 'download' related errors, be SURE to upgrade your (public) BOINC core client to version 4.19 or your (experimental) BOINC core client to version 4.59 or greater..

The LIGO Scientific Collaboration Calibration Team has released the final (v3) calibration information for the S3 data run

The LIGO Scientific Collaboration Calibration Team has released the final (v3) calibration information for the S3 data run. In the next several days we will be replacing our current search data set (which uses the v2 calibration) with the v3 version.
