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.
