| | 14 | * Detection efficiency: merged branches/pap into trunk, r25383. |
| | 15 | * PS1SC: |
| | 16 | * Set up nightlogs@ps1sc.org list |
| | 17 | * Organising UK tour |
| | 18 | * Retrieved and sent dravg archive |
| | 19 | * Stacking: |
| | 20 | * Everything was getting rejected. Turned off "additional variance" in pmStack, and get decent rejections now. This is not well understood yet, but may be connected with a change made a month ago removing the "variance factor" terms, or renormalising the image subtraction chi^2. |
| | 21 | * Can identify bad images using the iq statistics calculated in psphotImageQuality.c: iq_m2, iq_m2_uq-iq_m2_lq, iq_m3 and iq_m4 are useful quantities. |
| | 22 | * Sent Nigel and Peter a dump of ThreePi data from June/July that should be useful for determining good cuts on these quantities. |
| | 23 | * High-frequency structure in kernels caused by minimum ISIS width = 1 (FWHM, not sigma!): fixed ppSub recipe |
| | 24 | * Increased rejection threshold (COMBINE.REJ) to 2.5 from 2.0 standard deviations. |
| | 25 | * Using a given analytic PSF instead of that produced by pmPSFEnvelope produces reasonable results for the stack. Attempting to correlate resultant convolution kernels with iq statistics. |
| | 26 | * Fixed fuzz of FITS images so that expectation values are preserved (trunk@25439), after help from http://fits.gsfc.nasa.gov/registry/tilecompression.html |
