Alexander Data Collection

Alexander Data Collection

We used a Python program in order to collect data and analyze it as well. Soon, the custom Python program will be available on GitHub for others to download and use as well. For now, we are listing the basic steps in order to collect and analyze your data.

Using the Telescope for Data Collection:

1) Connect your AirSky to both the telescope and your computer


2) Add to Python Path (will eventually be available either on this WikiPage or GitHub)


3) Access the watch program (watch.py)


4) Calibrating cold load: point the telescope away from the Milky Way Galaxy in order to take the cold load measurement


5) Calibrating hot load: point the telescope towards the ground in order to take the hot load measurement


Data Analysis:

1) To open data in Python:


cd data


ls


mkdir20170726 (<<the date is arbitrary; e.g. we took data on July 26th, so we used the command mkdir20170726)


mv 2017-07-26* 20170726


ls


ls 20170726


cd ..


ls


R data/20170726/*.ast (<<ast means astronomical data, so the hot loads and calibration are not included in the data; do not include .ast if you wish to access the hot load data as well)


ls


python sum.py 300 data/20170726/*


GO RA data/20170726/*.sum


GO RA 2017-07-26*.sum


GO GAL 2017-07-26*.sum
