+    LightCurve{T}
+
+A structure representing a light curve, which is a time series of event counts.

+## Fields
+
+- `timebins::Vector{T}`: Time bins for the light curve.
+- `counts::Vector{T}`: Number of events in each time bin.
+- `count_error::Vector{T}`: Error estimate for each bin.
+- `err_method::Symbol`: Method used for error estimation (`:poisson`).

+    create_lightcurve(eventlist::EventList{T}, bin_size::T; err_method::Symbol=:poisson)
+
+Generate a light curve from an EventList by binning event times.
+
+## Arguments
+
+- `eventlist::EventList{T}`: The input event list.
+- `bin_size::T`: The size of each time bin.
+- `err_method::Symbol`: The method for error estimation (`:poisson`).
+
+## Returns
+
+A LightCurve instance containing binned event counts.
+
+## Notes
+
+- The function bins event times into intervals of `bin_size`.
+- Errors are estimated using Poisson statistics.
