Parameters: RESPONSE command |
Parameter |
Description |
STD |
Raw Standard star, in STANDARD reduction mode. |
RESPONSE |
Computed instrument response in STANDARD reduction.
If the name NULL is assigned to this parameter no
response correction is applied in the REDUCE command.
Instead, the blaze function is fitted. |
FLUXTAB |
Table with absolute fluxes for the Standard star,
in STANDARD reduction mode. The tables are in the area
MID_STANDARD |
FILTMED |
Radius in x and y, threshold, as in command FILTER/MEDIAN
used to smooth the response function. |
FILTSMO |
Radius in x and y, threshold, as in command FILTER/SMOOTH
used to smooth the response function. |
PIXNUL |
Number of pixels to set to zero at the edges of each order. |
BKGxxx |
All background parameters : see definitions in Table 7.8) |
FFOPT |
Flat-Fielding option ( YES/NO) |
CORRECT |
Flat field correction image (required if FFOPT=YES). |
BLAZE |
Smoothed flat field (required if FFOPT=YES). |
EXTMTD |
(See definition in Table 7.7) |
SLIT |
(See definition in Table 7.7) |
OFFSET |
(See definition in Table 7.7) |
SAMPLE |
(See definition in Table 7.7) |

RESPOPT |
Option for the response corection ( YES/NO). |
RESPMTD |
Method for the instrumental response correction ( STD, IUE). |
RESPONSE |
Name of the response image as produced by RESPONSE/ECHELLE
(required if RESPMTD=STD). |
RIPMTD |
Defines the ripple correction algorithm as SINC for the method
fitting the blaze function, described by Ahmad(1981), and as
OVER for the method using the overlapping region of the orders,
proposed by Barker (1984) (required if RESPMTD=IUE). |
RIPK |
Defines the initial guess for the parameter k
in Equation 7.5.
The default value is updated during the wavelength calibration. |
ALPHA |
Defines the initial guess for the parameter
in
Equation 7.5. |
MGOPT |
Merging option ( YES/NO). |
MRGMTD |
Merging method ( AVERAGE, NOAPPEND). |
DELTA |
Interval (in wavelength units) to be skipped at the edges of each order. |
