Stripes 1100 Footprint Anomaly

There is a defect in the footprint along stripe 1100 from 320 > RA > 300 and 0 < DEC < 10 :

Here is a possible SQL for recovering these objects (to do both in the context dr7 and Runsdb) :

Select p.run,p.rerun,p.camcol,p.field,p.obj,p.ra,p.dec,g,mode,p.status,stripe,strip

From Photoobjall p,field f,segment s

Where

Ra between 320 and 300 and

Dec between 0 and 10 and

G between 18 and 18.2 and

p.fieldid = f.fieldid and f.segmentid = s.segmentid

(and mode=1 for the context dr7)

With this, we can select the interesting data in Runsdb keeping the data from Runsdb :

$11 ==1100 && ( ($4>398 && $12 ==1) || ($4 >381 && $12 == 0 ) )

The South strip of Stripe 1100 from the runsdb consists of objects from run 4832.

The North strip of Stripe 1100 from the runsdb consists of objects from run 4828.
