+
+=== Data Registration ===
+
+I've defined a database 'vysos5' in mysql on vysosdata1, and am using that to track the VYSOS5 science processing.
+
+All of the raw science images are stored in /drobopro/vysos/VYSOSData/VYSOS-5-Data/Images, which is linked to /home/ipp/alldata.  
+
+I injected all of the science images using a script which basically looks like this:
+{{{
+foreach f (alldata/200?????)
+ set subdir = `basename $f`
+ ipp_serial_inject.pl --telescope vysos --camera vysos --workdir path://PROCESS/$subdir --end_stage reg --dbname vysos5 $f/*.fts
+ ipp_serial_inject.pl --telescope vysos --camera vysos --workdir path://PROCESS/$subdir --end_stage reg --dbname vysos5 $f/flats/*.fts
+ ipp_serial_inject.pl --telescope vysos --camera vysos --workdir path://PROCESS/$subdir --end_stage reg --dbname vysos5 $f/Calibration/*.fts
+end
+}}}
+
+I ran the registration process on the images injected into the database.  There are currently 20796 science images and 7819 detrend images.  
+
+I am generating a master BIAS frame.  An unfortunate aspect of the VYSSO5 headers means that the DARK and BIAS images have invalid times (1970/01/01).  This makes it difficult to control which input images are used to make a master.  I have used a random sample for this initial pass, in the assumption that the camera is reasonably stable.
+
+Command to generate the basic master BIAS:
+{{{
+dettool -dbname vysos5 -definebyquery -random_subset -random_limit 25 -workdir path://PROCESS/detrend/bias -inst VYSOS5 -det_type BIAS -select_exp_type BIAS
+}}}
