3D related information for points on module sides (FEs) for bow/inclination measurements.
Currently SIDE and C0/C7/C8/CF/P0/P7/P8/PF keywords are different. So if someone measured 3D coordinates of C7 cross, they must be written twice – with C7 and SIDE keywords.
Raw survey data file

Raw data file is an input for PYTHON program (runs on WINDOWS. Must work on LINUX without any changes but not checked yet). It produces all final survey data – positions, rotations, bows, etc.
Raw survey data treatment
XZ plane information is obtained by fitting module crosses/pads measurements with geometrical model.

In addition in the printout of the program one may find the deviations of measurements from ideal positions to check quality of the data

For bow measurements all points ( with SIDE key) in ONE side of the module (with X<0 or X>0) are considered as points in YZ plane. They are fitted in this (YZ) plane with a circle. Bow is calculated based on curvature and cross-cross distance. Inclination angle is calculated as a direction from module center to the circle center.
Raw survey data treatment
Again in the printout of the program one may find the deviations of measurements from ideal positions to check quality of the data:

You need PYTHON and SciPy (PYTHON package for scientific calculations). The simplest way is to install them from ATLAS physics analysis web page: http://www.usatlas.bnl.gov/PAT/
RAW survey data file may be produced by hand (not a very complex format indeed) or with a simple PYTHON script from any favorite CMM/Excel/whatever file for each site. This is already done in Genova for bare CMM text files RAW survey file conversion. ( I’m ready to provide a PYTHON script. But if someone wants to have a converter in C++ or VisualBasic …)
Any part of RAW data file (except for rubyballs) may be missing. Minimal numbers of points per module for successful fit are 2 in XZ and 3 in YZ planes.
It’s very easy to add a new option ( switching mm/micron, arbitrary error for each measurement, new output) . Any suggestions?
