Description
In some case for DECam catalogues I noticed that the cross match contrast with Gaia DR2 is very high when I process the file alone, but very low when I process it with other files.

In the dataset, you can see that file ct4m20170516t004358-V4.1-ooi.cat
has a contrast of 3.76 when scamped with the rest, and 78.2 when processed alone.
This is with scamp v2.9.2
