| ALGORITHM |
Description of algorithms: median_master: median level of master screen flat within X200...1800, Y400...800 (MIDAS stat/ima; outputr(8)) sigma_master: std.dev. of master screen flat within X200...1800, Y400...800 (MIDAS stat/ima; outputr(4)) | |||||||||||||||||||||||||||
| CERTIF |
Reasons for rejection: - unusual structure; Smooth, large scale variations, individual bright/dark spots in the central area of the ratio master/reference are no reason for rejection. | |||||||||||||||||||||||||||
