Introduction
This do cument presents the information on the use of the MASS Software. It is created for the control of the op erations with the Multi-Ap erture Scintillation Sensor device designed at Sternb erg Astronomical Institute, according with a Prop osal to CTIO [1]. The pro ject was implemented in frame of the AURA contract No. C10389A. While the MASS-DIMM device incorp orates two instruments in one b ox, the software describ ed here do not take into account existence of the DIMM channel of the device which is controlled by the different program. The do cument consists of several Chapters first of which presents an overview of what can b e done with the program and what are the general ideas of implementation of its functionality in form of its modes. Next chapter is more practical ­ it describ es how to install and prepare the software for a particular use. Chapter 3 tells ab out the comp osition of the program interface and gives more details on how the device works in its numerous mo des and which settings affect its p erformance. Chapter 4 describ es in brief the usual observational sequence (details are given already in previous chapters) and explains the data output in details. Finally, the last chapter 5 gives a helpful list of changes intro duces in the version 2.04 of the program Turbina which resulted from the first exp erience of automated way of use of the device. The drawbacks which still p ersist are mentioned as well. Compared to the previous versions of the current do cument, more details and practical advises are given, which allow to call it a real User Guide for the first time.

MASS software operation overview
1.1 Main features of measurement pro cess with MASS instrument

The software for control of MASS op erations and data acquisition and reduction provides b oth reliable scintillation indices and atmospheric turbulence profile measurement and an ease of control and handling. The software supp orts all op erational mo des needed for making measurements, including testing, calibration and auxiliary measurements. In order to measure correctly scintillation indic
