  1. Searching SN -- SSN 2004年7月1日星期四

  2. # Here We give a general pipline(s) of SSN. # version 2.0 acoording to *.csh codes. ----------------------------------------------------------- Check upload dir for new data & archive data | | Find reduction ID of new data copy them into workspace | 'cob50' <== 3 (or more) image --> sn01.fit | | make projection with respect to template.fit --> sn.fit template.fit | | | V | catalog & -> 'newcrrb' --->| (optional) mask regions | Background crrected image: clean_crrb.fit |

  3. | (Catalog Matching) LINE 2 ----- LINE 3 (Variables) | LINE 1 (Subtraction) | Find the difference in Seeing and blur one image by iraf for the aim that equivalent-seeing subtraction | template.fit | experimented 'Kernel' & its v.s. -> See'_diff --->|<--- variation over CCD clean_crrb.fit | |<--- Mask known stars with | a definite catalog of stars (DCS) | subIMG = clean_crrb.fit - template.fit(Seeing_corrected) --------------------------------------------------- | Reject the black rings --->|?<--- de-noise (wavelet + 921trans) (by fitting a PSF | or double-gaussian) |

  4. | from LINE 2 --+-- from LINE 3 | | Candidates | Sort by goodness of fitting ->|<- Sort by dsitance to galaxies | | | (Need the DCS) ~10 or less Cadidates | | - generate cadidate figures and webpages and publish them; - inform colleagues for a check by emails.

  5. Future Plan • 空间采样不足。  • 暗弱的SN。  • 靠近星系的候选体  • 亮的SN（SNR > ~10）  • 减少候选体 
