Calibrated meudon data

This repository contains calibrated filament data which is made from Meudon hand drawn archive, which consist hand drawn Carrington maps in image format available at BASS2000: Solar Survey Archive at Observatoire de Paris (available at http://bass2000.obspm.fr/lastsynmap.php). The Meudon archive consisting gray scaled images for Carrington rotation 876-1823 and coloured images for Carrington rotation 1824-2008. After downloading the data from the Meudon archive, we have used a automated method (described in our paper which is accepted for publication in APJ and now available at https://arxiv.org/pdf/2106.04320.pdf) to calibrate these data and then we have used these calibrated data for further studeis of solar filaments. These calibrated data from our automated detection is now we are making public and can be used for any further studies only after citing our paper Mazumder et al 2021.  Data of gray scaled images for Carrington rotation 876-1823 is kept at gray_scale_image.zip folder and data for coloured images for Carrington rotation 1824-2008 is kept in colour_mages.zip folder.
