Array Data Desired:
70um and 160um Arrays
Data Reformatting Option:
Special Instructions:
From each pair of 1 DCE and 277 DCE exposures, a single FITS file should be produced including all 278 files. A single FITS file should be produced from each 50 DCE exposure. These two sets of exposures will be repeated ten times, so we should get 20 FITS files for each array.
1) Median stim brightness, averaged over all 47 stim flashes, tabulated and plotted as a function of array bias 2) Stim repeatability, determined by using the odd-numbered flashes to calibrate the even flashes, reported and plotted as a function of bias 3) Stim-calibrated dark level, tabulated and plotted as a function of bias 4) Read noise, tabulated and plotted as a function of bias 5) A report listing the optimum bias voltage for each array, along with an explanation of how the input criteria led to this selection
Step by step analysis: 1) Run all data through "mips_sloper -a flight_ce# -l filename" and "mips_caler -d filebase" Include the illumination correction (do not use the -i flag and make sure that the IC is enabled in Pipeline/Cal/PreFlight/mips_caler.param). 2) Tabulate and plot the instantaneous stim flash brightnesses from mips_caler as a function of stim flash number (47 flashes), with different plot symbols for the five different biases. The IDL routine for doing this is mips246_stimcal, ymin=xx, ymax=xx. This routine also calculates a mean and standard deviation for the stim flashes. In addition, it calibrates odd flashes with evens and gives the standard deviation of the stim-calibrated flashes. It looks for all .cal.fits files in the current directory and processes them. It uses a different plot symbol for each. It is possible that we will get useful data when the other array is prime, so all 10 data sets should be reduced for each array. The variables numstims and firstStimOffset need to be set properly in the .pro file before using this tool. 3) Use the tool mips246_darkcal,'filebase',ymin=xx,ymax=xx,skip=xx for calculating stim-calibrated dark levels. This tools works from .cal.fits files. The output values are stim-normalized and so will likely have values less than 1. "skip" is the number of DCEs to ignore after a stim flash when calculating dark levels. It is best to let that keyword default to 0 initially and then set the keyword appropriately on a second pass, based on the latent behavior observed in the output plot. The mean brightnesses calculated by this routine are stim-normalized, so they need to be multiplied by the stim brightness values from mips246_stimcal to get dark values. Several keywords need to be set appropriately in the .pro file before performing the analysis. These include: calcycle, numstims, firstStimOffset. 4) Use get_rdnoise, n_dce_rej=10, 'filebase' to calculate the Ge read noise. Reference noise levels for the nominal biases can be found in the cookbook for mips-226. 5) Plot stim brightness, dark current, read noise, and stim repeatability versus detector bias 6) Use a TBD method to combine the above results into a figure of merit for determining the optimum bias setting for each array
mips_sloper mips_caler for determining stim brightnesses mips246_darkcal.pro for determining the dark current levels mips246_stimcal.pro for determining the stim repeatability, using odd flashes to calibrate even flashes get_rdnoise.pro for determining the read noise
