一些Ashot策略有"simulator"词，它们之间有什么区别？

Question

我一直在Ashot Library和Browserstack API上使用Selenium，以获取设备的屏幕截图。并且通过射击策略，我注意到有一些可用的策略有"模拟器"策略。

Ashot库的文档很少：/

public static ShootingStrategy iPad2WithIOS8() {
    VariableCutStrategy cutStrategy = new VariableCutStrategy(41, 65, 960);
    return viewportNonRetina(500, cutStrategy);
}
public static ShootingStrategy iPad2WithIOS8Simulator() {
    VariableCutStrategy cutStrategy = new VariableCutStrategy(41, 65, 1250);
    return viewportNonRetina(500, cutStrategy);
}
public static ShootingStrategy iPad2WithIOS8Retina() {
    VariableCutStrategy cutStrategy = new VariableCutStrategy(41, 65, 960);
    return viewportRetina(500, cutStrategy, 2.0F);
}
public static ShootingStrategy iPad2WithIOS8RetinaSimulator() {
    VariableCutStrategy cutStrategy = new VariableCutStrategy(41, 65, 1250);
    return viewportRetina(500, cutStrategy, 2.0F);

每个中的每个都有一个模拟器版本。有人知道它们有什么区别吗？

也许是因为其中一个用于仿真，而其他设备也用于真实设备。
