7:48 Friday January 11, 2002. I think that the quadrature detection scheme is now correct. I have to get it programmed right, run the programs for a lot of data, etc. I also have to be ready to download the rest of the PSM data, when Andy puts it on the site. I have used about 2/3 of the 32-MB hard disk on Abdus. I'll have to delete some files pretty soon. I would like to have a backup system which rereads the files to verify them. Maybe Dan can tell me how.
