 More information on meedium deep u band stacks
 
+There is a problem in making the medium deep u band megacam stacks - it worked fine when Gene did this in 05/2011, but now it doesn't (why). I've done some investigations, it appears to be the recipes:
+
+Ingredients:
+
+ * make a stack of all the uband warps with this label: u.MD01.20110602
+ * use different combinations of code or recipes to figure out what's wrong
+
+First, I checked out the trunk at r31601 (which is the r that gene's processing claims to be, except on the eam branch). As it was, it didn't have the correct recipes for TEST1 for megacam, so I copied over the ippconfig from the current trunk (r33784). I did various iterations of different ippconfigs (from back then to now) and trunks (from then to now). Here's a summary:
+
+
+
+ || branch/trunk? what? || ippconfig?  || result ||
+ || trunk r31601        || trunk r33784 || bad stacks ||
+ || eam branch 20110505 -r31601 || trunk r33784 || bad stacks ||
+ || eam branch 20110505 -r31601 || eam branch 201105 (r31657) || good stacks ||
+ || trunk r33784        || trunk r33784 || bad stacks ||
+ || trunk r33784        || eam branch 201105 (r31657)    || good stacks ||
+
+So, from this I conclude that there's something in the recipe. I need to investigate this: the log files indicate no (or little) difference in the recipes, but basically only include ppStack's recipe. It turns out when stacking it also uses ppSub and other configurations, and I need to be more careful and investigate the mdc files to determine what's changed...
+
+However, I present some pictures (as proof) of the good/bad stacks:
