Summary of grid tests

I put some important information in brackets: {ZA,parallactic angle}
Unless otherwise stated, wires were vertical

A Jan 8; Jupiter, hwp=20 {40,-30} 27943-6 LAST FILE IS FIRST ANGLE
B Jan 9; Saturn hwp=20, {near transit} 28069-72
C Jan 10; Jupiter, hwp=30 {35, -10} 28473-6
D Jan 10; Jupiter, hwp=20 {35, -10} 28477-80
E Jan 11; Mars, hwp=35 {15, -80} 28482-5
F Jan 11; Mars, hwp=35, wires rotated 45 deg CW {15, -80} 28486-9
G Jan 12; Saturn, hwp=35, wires rotated 45 deg CW {10, -80} 28907-10
H Jan 12; Saturn, hwp=125, wires rotated 45 deg CW {10, -80} 28911-14
J Jan 13; Saturn, hwp=35, {near transit} 29170-73
K Jan 15; Jupiter, hwp=35, {40, -40} 29876-79

Analysis:
                                                                                
From doing eyeball estimates of the position of the peak in H-V, and 
(empirically) adding 22.5 degrees to the ones with wires rotated by 45 
degrees CW, I get the following numbers for the peak in H-V:
                                                                                
50, 55, 45, 55, 50, 57.5, 47.5, 47.5, 50, 50

mean: 51
std. dev: 4

The mean of the first five values is 51 also, so there is no evidence of 
any long term drift.
