Mosaic Data Collecting
● Separate snapshots put together to make one picture
● Camera pointed in different directions○ Have to make up for the camera “sagging”
■ take off time drift

Picture of Data
![Page 4: Microwave Kinetic Inductance Detector - QuarkNet€¦ · Microwave Kinetic Inductance Detector By Natalie Forsberg. Mosaic Data Collecting Separate snapshots put together to make](https://reader033.fdocuments.us/reader033/viewer/2022053007/5f0b24017e708231d42f0cb4/html5/thumbnails/4.jpg)
Information on the Data Picture● Right ascension
○ East to West● Declination
○ North to South● Important numbers
○ 0, 45, 46, 55, 56, 101● blue lines = path of telescope
■ Use surrounding numbers’ info to piece together the snapshots

Use Position of the Center Object
● Calculate RA Dec drift from first and last exposures○ calculate camera rotation and degrees per
pixel for each pair of snapshots● Use the average to align all snapshots

Reference Star● Very important
○ Used to help put the mosaics together● It is located within multiple mosaics
○ Allows us to combine the mosaics into one great pic

Centroid● Finds center of star● It is a more accurate measurement
○ specifically the X and Y position of the object● We “guess” where the object it
○ to the closest integer■ then do a fit in order to get a better value
● What will we use it for?○ to calculate the rotation angle and plate scale○ more precision

What is TimeMask?
● It tells you what time a pixel went “crazy”● Used to help to see pixels, and ignore the
time when a pixel went bad○ If we ignored every bad pixel altogether, then we
would never see any pixels● If a pixel shoots up
○ gets lots of photons■ just that moment of time of the pixel is ignored

What is Interpolation?● Almost like photoshop
○ Takes the bad pixels■ “fixes” them
● Takes the value of the bad pixel and replaces it○ it does this by taking the average of the
values of the surrounding pixels■ then, it replaces the dead value with
the new value

How the Pictures are Colored
● Don't Forget!○ We have colored information
■ Key feature of MKIDs● We figure out what color the photons are
○ Assign them different wavelengths● Using George’s program I have created...
