Simulated Light Curves for Strong Gravitational Lensing

This mock dataset simulates light curves for strong gravitational lensing (optical data). Each file contains pairs of light curves with a time delay of five days (DS-5).

Table: Simulated Large Scale Data Sets

Noise	Gap Size 0	Gap Size 1	Gap Size 2	Gap Size 3	Gap Size 4	Gap Size 5
0%	1	10	10	10	10	10
0.036%	50	50	50	50	50	50
0.106%	50	50	50	50	50	50
0.466%	50	50	50	50	50	50
Sub-Total	151	1510	1510	1510	1510	1510

Total = 7,701 data sets per underlying function.
5 underlying functions yield 38,505 data sets.

File Naming Convention

Files follow this notation:

DS-5-<Function>-GAP-<GapSize>-<Realization>-N-<NoiseLevel>

Explanation of Components:

• DS-5: Indicates that the true time delay is five days.
• Function (<Function>): Represents the underlying function number (ranges from 1 to 10).
• GAP (<GapSize>): Indicates the number of removed points:
  • 0: No gap.
  • 1-5: Different gap sizes.
• Realization (<Realization>): Represents different random gap realizations (ranges from 1 to 10).
• N (<NoiseLevel>): Represents the noise level:
  • 0: No noise.
  • 1-3: Different noise levels.

Example

DS-5-1-GAP-0-1-N-0

• DS-5: True time delay of five days.
• 1: First underlying function.
• GAP-0: No gaps.
• 1: First realization.
• N-0: No noise.

Each pair of light curves is divided into five blocks before applying the gap procedure.
