Changes between Version 1 and Version 2 of Questions_Durham_MDS_Testing

-              v1
+              v2
 These questions are preliminary and will be updated as we learn more.
+) The width of the tracks removed by Magic are often extremely wide (10s of pixels) and result in up to 30?% of a given image be masked out.
+What is the prospect of getting Magic working within the specification of only a few percent masked pixels?
+) The width of the tracks removed by Magic are often extremely wide (10s of pixels). For example, in the 19 warped frames for skycell 077 in MD08 (g-band), between ~20-50% of pixel data in frames are masked out. What is the prospect of getting Magic working within the specification of only a few percent masked pixels? Note that bad read-out regions also result in large areas of individual frames being masked out.
+) We have measured the PSF of the stacked images [g-band MD08?] to have a width of 2 arc secs whereas the data distribution table [insert link] lists the image quality as 1.2 arc secs. Why is it so bad (especially as the stack is made from only the 50% best data) and why
+is the quoted 1.2 arc sec wrong.
+) We have measured the PSF of the stacked images (g-band MD08) to have a width of up-to and over 2 arcsecs whereas the data distribution table (PS1_Science_Processing_Status_20090705) lists the image quality as 1.2 arcsecs. Why is it so bad (especially as the stack is made from only the 50% best data) and why is the quoted 1.2 arcsec wrong?
