Fit results
Distance between 2 peaks in Arc region
Radius of the median point of 2 peaks in Arc region
Fit results for phi and beta in EQU region
Fit results for for phi and beta in ARC region
Negative solution y = -B - sqrt(B*B-C)
y = funcy_l1(x, phi_deg, bet_deg, DoR=392/913.27, sgnrt=-1.)
Positive solution y = -B + sqrt(B*B-C)
y = funcy_l1(x, phi_deg, bet_deg, DoR=392/913.27, sgnrt=+1.)
The number of events with well defined angular errors in the fit is rughly half of all events...
beta distribution is shown for 0.1<beta_error<100
Phi-beta function to fit
pyimgalgos/src/FiberAngles.py
y = funcy_l1(x, phi_deg, bet_deg, DoR=392/913.27, sgnrt=-1.)
Two solutions of quadratic equation
- POS: y = -B + sqrt(B*B-C)
- NEG: y = -B - sqrt(B*B-C)
Legend:
- dot curves for negative beta
- black bold curve for beta=0
- solid curves for positive beta
Arc region
- For beta>27 solution does not exist...
Equatorial region
- For |beta}>45 solution does not exist...
