SkyOffset (Illumination) Correction |
 |
Below are blinks between L1a frames that were corrected with a relative
sky-offset and those without. The sky-offset was made from a trimmed average
of 70 consecutive frames and re-baselined to have zero median.
This was then subtracted from the input frames.
The field below is at galactic
long, lat: 291, -2.62 deg, frameset ID: 01133b245.
W3: NO skyoffset vs. WITH skyoffset correction
W4: NO skyoffset vs. WITH skyoffset correction
Same field as above. Note the (short-term) latent at upper right.
