v79 v80 51 51 * hard limit on number of inputs (was shell descriptors limit of 1024 easily being reached with image,mask,weight,psf,cmf files for each input. Raised to 65535 now by default.) 52 52 * selection of target PSF FWHM, worse input PSF not necessarily best choice as could end up being rejected and only a few inputs may be that large (not representative) 53 * heavy RAM use (10-20GB typical for 100+ inputs) 54 * long run-time for 20+ inputs, 400 inputs order 12-14hr (use method similar to psphotStack?) 53 * heavy RAM use (10-20GB typical for 100+ inputs) -- tests run unoptimized, will need to look at effect 54 * long run-time for 20+ inputs, 400 inputs order 12-14hr (use method similar to psphotStack?) -- tests run unoptimized, will need to look at effect 55 55 56 56 … … 375 375 == Target PSF: manually set and as not worst input image == 376 376 377 want to look at NOT setting the convolved stack target PSF based on the worst input. 378 379 have seen cases when the worse inputs are image rejected so in that case not a good idea to use anyways. 377 Want to look at NOT setting the convolved stack target PSF based on the worst input. Have seen cases when the worse inputs are image rejected so in that case not a good idea to use anyways. 380 378 * for large N, a rerun would be of little time cost or just reject outright as little input to final stack 381 379 * for small N may want to reject anyways 382 380 * instead of a rerun of target psf, could choose median psf or such and use poorer deconvolution to reject worse images anyways 383 381 382 What are the convolved stacks all used for 383 384 384 TODO 385 * will need to make a sample distribution of simulated PSFs, currently sample is flat. revise the making of the stack.mdc list of inputs 385 * will need to make a sample distribution of simulated PSFs, currently sample is flat. revise the making of the stack.mdc list of inputs. or will just be worse/upper limit of possible stack degrading for including deconvolved images. 386 387 SYS.ERR=0 change set, but effect comes after this stage so not important. 388 386 389 387 390 === manually set Target PSF === … … 403 406 ---- 404 407 408 409 405 410 = Monitor Modifications = 406 411 Should watch results of changes in nightly science products.
