Stripe 1356 Footprint Anomaly

There is a defect in the footprint along stripe 1356 from 50 > RA > 30 and -15 < DEC < -5 :

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 50 and 30 and

Dec between -15 and -5 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 == 1356 && $3 < 6 && ( ($1 == 6572 && $4 < 128 && $4 > 124) || ( $1 == 6591 && $4 < 142 && $4 > 139 ) || ( $1 == 7264 && $4 > 74 && $4 < 78 ) )

A zoom on this :

We can make a zoom to understand better what happen :
