The purpose of this project is to compare the manual filament chirality determinations of Yeates et. al. (2007) with the chirality determinations of the AAFDCC code written by Bernasconi et. al. (2005). This code is designed to detect, track and characterize filaments by extracting their various properties like size, chirality, etc.
The problem:
The AAFDCC code runs on .fits files of H-alpha observations from the Big Bear Solar Observatory (BBSO) which are available from 6th July 2000 to present. Whereas, Yeates et. al. have determined chiralities of filaments in the year 1999 from .jpeg images taken at BBSO. Therefore, there is no overlap in these datasets where we could make a comparison.
Project:
BBSO has been observing the Sun in H-alpha and Ca II since a long time. Their data stream stretches back to 1982, but it is rather discontinuous in the 1980s and the 1990s.
We are targeting the time period between 1997 and 2000 to come up with a routine that can convert the all corrected (FR) JPEG images to fits files with appropriate header information so that they can be analyzed by the AAFDCC code and we can compare the results of the code with the manual chirality determination by Anthony Yeates.
