Message from Rae:
I have prepared a snowflake of 13th magnitude stars around a
4th magnitude JCAT star found on image 56 scan 79 980202n.
The 4th magnitude star in JCAT is at 169.3529 22.8265.
Mags J,H,K are 3.5,3.6,and 3.8. The borrowed star is at
169.335036 22.872784 in 2MASS IDR2. Catalog mags of borrowed
star are J,H,K 11.323, 10.872, 10.826.
The files are named {jhk}fkmag4.rdo and are on holly:/k2/ftp/north.
The original files are {jhk}0339079.rdo.
Please analyze the fake file and add the analysis to the web page that
has the mag 6 and 8 snowflake analysis on it.

The following images show J, H and Ks
Atlas Images with artificial 13th mag stars placed in a snowflake
pattern around the primary Ks=3.8 star.
The table below lists extracted positions and
JHKs magnitudes and errors of the
simulated stars in the snowflake pattern.
All simulated stars
were detected in the pipeline EXCEPT for the
innermost ring at 5 arcsec separation where TWO of them were detected.
Along each arm of the
pattern, stars are separated by 5 pixels, and the source names refer
to the arm and position from the primary.
Positions, magnitudes and errors
are listed along with the following flags: Read, Blend,
Persistence, Glint, Diffraction and Confusion.
The table below lists extracted positions and
JHKs magnitudes and errors of the detections
associated with the
primary star within 5 arcsec of the center.
The detection closest to the center of the primary
is the first object listed.
