Hi all I'm going over the GSAS data format (by reading the manual), trying to figure out how it works, and I've come up with a couple of questions:
1) In a STD data set, the manual says that NCTR is the number of counters and YO is the n number of counts per counter. So, for a single data point " 3 3452", is the total counts =3*3452? What is the error? Sqrt(3*3452), 3*sqrt(3452) or sqrt(3452/3)? 2) What is the data format for type = "ALT"? The manual (http://www.ccp14.ac.uk/ccp/ccp14/ftp-mirror/gsas/public/gsas/manual/GSASManual.pdf) doesn't say...
