MASCARA-1 b Archives - Astrobiology

ONC-T images of (a) WASP-189 (image hyb2 onc 20240918 073620 tif l2b) and (b) MASCARA-1 (image hyb2 onc 20241130 093826 tif l2b) captured during transit events 10 and 12, respectively. The left panels show a single reduced ONC-T image (p t (x, y)) without hot pixel correction (i.e., data reduced assuming phot = 0 in Equation 1). The center panels show the same reduced images with hot pixel subtraction. The right panels show the reduced ONC-T image after applying a 3 × 3-pixel median filter and stacking all frames co-aligned on the target star, allowing the stellar positions to be clearly visualized. The host stars are marked with circles. -- astro-ph.EP
