Spectrograph

Simply decide whether you want to use the LMR positioners or the HR positioners.

Target file format

Target file should follow the format indicated below. The simulator will reject any file that does not look like this, for safety reason.

• The columns should be in the order shown, with the sizes shown.
• The coordinates should be entered in degrees.
• The coordinates can be provided as Equatorial, Galactic, or Ecliptic. However, please use the same reference if you decide to manually enter the center of the field of view.
• The Priority numbers are integer numbers, one per target, which indicate how important a target is, relative to other targets in the list. The higher the score, the higher the priority.
• The Repeat numbers are integer numbers, one per target, which indicate how many times a target should be allocated before it is considered observed. This can be used, for instance, to simulate the fact that some faint targets will require more observations.

Field of view center

By default, the simulator will automatically use the mean of all RA and all DEC in the input catalog as the center of the field of view. If you wish to set the center manually, you can do so by providing the RA and DEC coordinates of the center, in degrees (or Galactic longitude/latitude if you provided a list of targets in this WCS).

Computing method

The simulator has three modes: "one allocation", "fixed number of iterations", and "goal: allocation fraction".

• "one allocation": the simulator will just run once, and return the fraction of allocated targets after that one iteration.
• "fixed number of iterations": the simulator will run as many times as you decide and return the fraction of allocated targets after each iteration.
• "goal: allocation fraction": the simulator will run as many times as necessary to reach the allocation fraction you enter and return the fraction of allocated targets after each iteration.

The computing time scales with the number of targets and number of iteration necessary. Please be patient. Your results will appear below.
