Major Categories of Systematic Error for Interference Paper:
(as per SK suggestions)
- Theory which SK will estimate (currently two papers out regarding theory)
- Fitting(i.e. polynomial vs. 1/t fit)
- Check out SK QM writeup for further discussion of systematics.
Another suggestion about systematics was to scale the error bars by a factor of [sqrt(2)/(chisq/dof)] to get a better overall fit, as per particle data group procedure. Though this is not ideal, since they take a bunch of independent
measurements and perform a fit. Obviously this is not what we're doing.
Setting Up StarClassLibrary on Nuclear
As per Manuel's request I attempted to setup StarClassLibrary on nuclear.
- Checkout the Library on RCF
- klog bhaag -c rhic.bnl.gov -or- klog -c (if you're on rcf)
- cvs co StRoot/StarClassLibrary
- tar it -- tar cvf filename.tar
- Put it on Nuclear.
- In order for everyone to see it, it should be placed in nuclear (NFS mounted)
- One place for libraries is: /usr/include -- but is it NFS mounted? Probably
- Need to complile the library...or do we?
- Date is not correct, so AFS is not working apparently.
- If AFS was working, we could establish the environment variables to look
to BNL and get ROOT as well as cons, so that we could compile the Library.
- Steps for this --
1. setup softlink: /opt/star -> /afs/rhic.bnl.gov/opt/star/
2. put script into proper directory to set environment variables.
3. save script as .csh file and run script in directory(/nuclear/usr/include)
4. need AFS to be working at this point...
- Currently the Library is sitting there, uncompiled. Not sure if anyone else can 'see' it.
