SIMPLE = T / Fits standard BITPIX = 16 / Bits per pixel NAXIS = 0 / Number of axes EXTEND = T / File may contain extensions COMMENT FITS (Flexible Image Transport System) format defined in Astronomy andCOMMENT Astrophysics Supplement Series v44/p363, v44/p371, v73/p359, v73/p365.COMMENT Contact the NASA Science Office of Standards and Technology for the COMMENT FITS Definition document #100 and other FITS information. CALFTYPE= 'PARM ' / Calibration file type CALFVERS= 15 / Calibration file version DETECTOR= '2B ' / detector (1A, 1B, 2A, 2B) EFFMJD = 50000. / Date on which file should be applied (MJD) DATE = '2006-11-30T17:33:00' COMMENT COMMENT The SPEX_SIC and SPEX_LIF keywords allow the user to center the extracCOMMENT tion windows along a given row rather than having the pipeline try to COMMENT centroid the spectrum. A number less than 0 or greater than 1023 willCOMMENT default to pipeline centroiding. A value between 0 and 1023 will defCOMMENT ine the center of the extraction window. Since the pipeline expands hCOMMENT istogram images out to 1023 pixels in Y, the number must be given for COMMENT a full 1023 image height. That is, if the center is determined from bCOMMENT inned images, the center must be multiplied by the binning factor befoCOMMENT re entering it in this file. COMMENT SPEX_SIC= -1 / SiC extraction window Y center (0-1023) SPEX_LIF= -1 / LiF extraction window Y center (0-1023) COMMENT COMMENT The EMAX_SIC and EMAX_LIF keywords allow the user to limit the amount COMMENT that the pipeline can shift the extraction windows based on the centroCOMMENT id of the spectrum. In cases where the source is very faint, the centCOMMENT roid routine may find bright detector artifacts or other apertures insCOMMENT tead of the desired aperture. If the calculated centroid differs fromCOMMENT the predicted centroid by more than EMAX_SIC or EMAX_LIF, the pipelinCOMMENT e uses the default extraction window location. COMMENT EMAX_SIC= 40 / SiC extraction window maximum Y movement EMAX_LIF= 40 / LiF extraction window maximum Y movement COMMENT COMMENT The following keywords allow the user to skip various COMMENT steps of the pipeline. Change value from 'YES' to 'NO' COMMENT to skip the corresponding step. COMMENT RUN_PHAX= 'YES' / PHA X correction RUN_BRST= 'YES' / Burst rejection RUN_JITR= 'YES' / Jitter correction RUN_ASTG= 'YES' / Astigmatism correction RUN_BKGD= 'YES' / Background subtraction RUN_OPTI= 'YES' / Optimal extraction COMMENT COMMENT These keywords control the jitter-screening routine. Only tabulated COMMENT pointing errors with quality flags greater than TRKFLG are considered.COMMENT Times when the pointing errors exceed the allowed limits are flagged COMMENT as bad. Limits are applied to both the LiF and SiC channels. COMMENT TRKFLG = 1 / Minimum trustworthy value of TRKFLG DX_MAX = 30 / [arcsec] Allowed pointing error DY_MAX = 30 / [arcsec] Allowed pointing error COMMENT COMMENT These keywords allow the user to specify the range and bin size of COMMENT the output wavelength array. If not set, default values are used. COMMENT LIF_W0 = / [A] Requested initial wavelength LIF_WMAX= / [A] Requested final wavelength LIF_WPC = / [A] Requested wavelength per channel SIC_W0 = / [A] Requested initial wavelength SIC_WMAX= / [A] Requested final wavelength SIC_WPC = / [A] Requested wavelength per channel END
