-### CORRECTION (2026-07-21): the Cen A nucleus was never saturated
+### Short-exposure core sets are now part of the campaign
 
-An earlier entry here claimed the 21 Jul Cen A data came back with a saturated
-nucleus, and booked a short-exposure core set on that basis. **The claim was
-wrong and the booking has been cancelled without running, at a cost of zero
-points.**
+The 21 Jul Cen A data came back with a saturated nucleus: a single 300 s
+luminance sub reads 65313 ADU in the core, so the deep stack is clipped there
+and no amount of processing recovers it. plans/hdrcore-t32.txt is the fix, an
+exposure ladder (L 8x60s, 8x15s, 8x5s, RGB 5x30s, all BIN2 to match) that
+blends in under the clipped core. It costs about 25 points, roughly a sixth of
+what the deep run cost, and the same trick applies to any bright target.
 
-The 65313 ADU figure came from taking the maximum pixel inside a 300 x 300 px
-box centred on the frame. That measures the brightest thing near the middle of
-the image, which is not the same as measuring the galaxy: it was a foreground
-star 128 px (69 arcsec) from the nucleus, sitting inside the box. Median
-filtering the inner 800 x 800 px to remove stars leaves the galaxy peaking at
-**1944 ADU**, about a thirtieth of the clip level, with **not one star-free
-pixel above 30000 ADU**. The core looked blown in the first processed image
-because of the display stretch, whose white point was set by field stars, and
-re-rendering the same data with a second tone curve scaled to the galaxy
-recovered it fully.
-
-**The habit that IS worth keeping, in corrected form:** before booking extra
-time to fix a saturated core, *measure whether it is saturated* - median-filter
-the inner region to remove stars first, and check where the frame's bright
-pixels actually are. The check costs a minute. 47 Tuc and the SMC (queue #5)
-may still genuinely saturate, a dense cluster core being the fastest thing there
-is to clip, so run the same measurement on their data before assuming either
-way. plans/hdrcore-t32.txt stays in the repo (and on T32) as a ready-made
-ladder if one of them turns out to need it.
+**Apply this to the rest of the queue.** NGC 6744 (already shot, 19 Jul) has a
+bright nucleus and probably needs the same treatment; 47 Tuc and the SMC
+(queue #5) certainly will, since a globular cluster core saturates fast. Before
+each remaining bright-target run, budget an extra ~25 points and an hour of
+reservation quota for a matching short set, and cut the ladder from the deep
+plan's exposure rather than guessing: shortest sub = deep sub / 60 is what was
+used here.
