GN-2005B-Q-7-52-003 | 2005-12-27 06:09:04 | offset p=0.31 manually since the centroid algorithm might be unreliable for an elongated object. SNe is visible at the edge of the galaxy, just where the finder indicates. I measured its center and offset this into the slit. |
GN-2005B-Q-7-52-004 | 2005-12-27 06:13:43 | offset was accidentally entered/ordered as p=0.031, so we adjusted by p=0.28 this image looks as if the SNe is not well centered, taking one more image to verify all is well setup |
GN-2005B-Q-7-52-005 | 2005-12-27 06:23:42 | object in slit, but not perfectly centered, performed one more 2 pixel offset, p=0.15 next will take spec sequence |
