Stripes 1100/82 Footprint Anomaly

There is a defect in the footprint along stripe 82 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 == 82 && (( $1 == 5654 && $12 == 0 ) || ( $1 == 5665 && $12 == 1 ) || ( $1 == 5675 && $12 == 0 && ( $4 < 70 && $4 > 44) ) || ( $1 == 5702 && $12 == 1 && ( $4 < 123 && $4 > 108 ) ) )

We can make a zoom to understand better what happen here.
