[Clas_cascades] Minutes Oct 28

[Kijun Park]

Hi Hovanes,

Here is my comments, most of them are minor.
Sincerely yours,
Kijun

Overall comments:
It looks to me that it's ready to be submitted.
(1) All figures need a caption "(color onlie)".
(2) Is it better if we have color Figure 1. ?

Details :
Page 1: INTRODUCTION
(1) Table 1. 5th row is experimental value. Caption said "selected model 
expectations"
(2) right-bottom paragraph: It seems that the reason of pentaquark 
search by photoproduction is based on Theta+ report, and only single 
calculation of photoproduction is available. I wonder whether we have 
actual reason that we examined the photoprodcution run for cascade 
experimentally or theoretically ? (I didn't read all previous paper but 
I guess they surely pointed out advantage of photoproduction)

Page 2: EXPERIMENT
(3) The the energy of the initial photon ... => The energy of the 
initial photon ...

Page 2: APPARATUS
(4) For this experiments we used... => For this experiment we used...
(5) ...reactions with final states with multiple charged particles. => 
...reactions of multiple particles in final states.

Page 3: ANAYLSIS-Evnet selection
(6) Just remind me, what \sigma cut on mass of lambda in Fig 2 according 
to 1.1108GeV < M_p\pi- < 1.1202GeV
(7) Only lambda cut is < (greater), others are <= (greater equal)
(8) Table 2. Summary of the event selection => Summary of cuts for the 
event selection
(9) Fig. 4 show the difference between ... => Fig. 4 shows the 
difference between ...

Page 6: ANAYLSIS-Trigger inefficiencies and normalization
(10) right-top : "We analyzed separately the events which latched the 
3-track... run-by-run basis."
         => This is already explained in previous paragraph.
