MOCCA Code for Star Cluster Simulation: Comparison with Optical Observations using COCOA

Understand

We introduce and present preliminary results from COCOA (Cluster simulatiOn Comparison with ObservAtions) code for a star cluster after 12 Gyrs of evolution simulated using the MOCCA code.

• The COCOA code is being developed to quickly compare results of numerical simulations of star clusters with observational data.
• We use COCOA to obtain parameters of the projected cluster model.
• For comparison, a FITS file of the projected cluster was provided to observers so that they could use their observational methods and techniques to obtain cluster parameters.
