ridge Module

CUPID_V2.0

CUPID General Info     "cupid" Command     All Pipelines     All Modules     


This module will output a table containing the x,y positions of the peak.

The module is used in the following pipelines:     BCDX    COADDX    BKSUBX

Constant values:

-c   Explicitly select the ridge position (position percent).
default: search for peak      override allowed: 0.0 <= X <= 100.0

-f   The calibration table that codes the order to be extracted for each FOVID, the default ridge location, and the extraction aperture width at a fiducial wavelength.
default: ch0,ch2=../cal/psf_fov.tbl ch1,ch3=(none)      override allowed: users psf_fov.tbl file

-g   The width, given in plus-or-minus percent of the array in the cross-dispersion direction, to be searched for the peak, centered on expected position (for LO-RES only). e.g. if you wish to include 25% of the array to either side of the targeted position, giving you a total extraction width of 50% of the array, you would set a value of 25.0.
default: 25.0      override allowed: 0.0 < X <= 100.0

-ghi   Explicitly specify the high-end cutoff of peak search area
default: ch1,ch3=75.0 ch0,ch2 use -g      override allowed: glo < X <= 100.0

-glo   Explicitly specify the low-end cutoff of peak search area
default: ch1,ch3=25.0 ch0,ch2 use -g      override allowed: 0.0 <= X < ghi

-m   Number of points to use for median filtering (LO-RES only)
default: 5      override allowed: N > 0 (must be ODD integer)

-s   The number of sigma to require the peak to be above the mean (LO-RES only)
default: 3.0      override allowed: X >= 0.0

-v   Level of verbosity
default: 1      override allowed: N >= 0

Pipeline calibration files:

-i   Wavsamp file
default: appropriate wavsamp.tbl file in ../cal/      override allowed: name of user's calibration file

Pipeline namelist files:

-n   Namelist file
default: appropriate ridge.nl file in ../cdf/      override allowed: name of user's namelist file

Pipeline input datafiles:

-p   Input profile file (IPAC ASCI table file)
[pipeline datafile --- override not allowed]

Pipeline output datafiles:

-o   Output ridge file (IPAC table file) (contains x,y position of the peak for each order and wavelength)
[pipeline datafile --- override not allowed]

Pipeline datafiles updated:

      (none)
