Analysis using your original file

• Use Flat data which you prepared
• Use original flux scaling file

Use Flat data which you prepared

Please replace the data of counts in $home/hsc/CALIB/FLAT/[dateObs]/[filter]/[calibVersion]/FLAT*.fits. Use this data when you run reduceFrames.py, then Flat data you prepared are applied.

Use original flux scaling file

Flux scaling file is fcr-[visit]-[ccd].fits in $home/hsc/rerun/[rerun]/[pointing]/[filter]/corr/[tract] (for detailed info Mosaicing). You can define your own flux scaling due to rewriting fcr-[visit]-[ccd].fits.

Parameters you need to change in this data are fluxmag0, NOEFF, order, and C_0_0. The core parameter defining flux scale is fluxmag0. Based on fluxmag0, the flux of each pixel is scaled by fitting <order>-th dimentional plane function (the number of coefficient = NOEFF). For example, setting flux scale to 2 to entire CCD plane,

fluxmag0 = 2
NOEFF = 1
order = 0
C_0_0 = 0
