+2017.01.09 : EAM
+
+  * ppMerge : comment out a free (this introduces a leak and should be conditional)
+  * stacktool : sort the skycells used for a summary skycell by skycell_id to ensure lists match.
+  * psLib : 
+    psMetadata.c : F64 data needs to be printed with %g not %f
+    psFitsScale.c : allow quartile stats to return a sigma based on +/- 1-sigma range
+  * psastro : 
+    fit a mosaic-wide distortion model, if it exists (e.g., RA---ZPN), otherwise maintain the mosaic fit model
+    allow missing model for a given chip (e.g., model not defined for bad chips)
+    save the calibrated magnitudes in MATCHED_REFS (using measured zero point)
+    add ROT_PARITY concept to the astrometry model (defined sign of ROTANGLE)
+    tpa->fpa transformation needs to have more polynomial terms than fpa->tpa (where the fit is performed)
+  * ippScripts : add HSC to cameras not corrected for background (in camera_exp.pl, should be a recipe-thing) 
+    
+  * Ohana:
+    various changes to relastro, relphot, fakeastro, addstar, delstar, uniphot, photdbc, dvomerge which do not affect nightly processing
+    libdvo/coorops.c : upgrade ZPN to full terms (remove UKIRT exemption)
+    libdvo : add test galaxy models; add object / measure bits for GAIA, 2MASS, TYCHO, SDSS, HSC, CFH, DEC
+    libfits : do not allow gfits_modify, etc to match FOO to FOOBAR, etc
+    libkapa & kapa2 : change some hardwired numbers to enum values, allow names for e.g., -pt and -lt
+    opihi : 
+      unify random number seeding; 
+      allow user-defined names for header NAXISi keywords for imbox; 
+      fix csystem conversion of motions
+      allow sphere-based 2d matches (matches2d)
+      define some physical constants as variables at startup (e.g., M_PI, M_c, M_c_cgs)
+      
+  * psModules:
+    allow photometry-based match in astrometry : downweight photometrically discrepant values
+    add ZPN model
+    do not attempt to force CRPIX1,2 to be 0.0
+    support for ROT_PARITY
+    add some tracing for detrending
+    
+  * Nebulous & Nebulous-Server : changes to support proximity 
+  
+  * ippconfig : 
+    GAIA and HSC photcodes
+    support for ROT_PARITY and psastro photometry window
+    accurate HSC zero points
