slide2

# 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

|

slide3

|

(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) |

slide4

|

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.
