WFPC2 Calibration and Close-Out
نویسنده
چکیده
This work summarizes the overall calibration strategy for WFPC2, covering the design of the observational programs as well as analysis of the results and their incorporation into the calibration pipeline. This strategy comprises routine long-term calibration monitoring programs, including darks, biases, flat fields, photometric and astrometric monitoring, as well as special calibration programs such as CTE and PSF characterization, and photometric cross-calibration with ACS and ground-based systems. In addition, we discuss special close-out calibration programs planned for the remaining cycles of WFPC2 operation, and describe ways in which community input can play a key role in further defining these plans.

Bandwidth Stability of the WFPC2 Narrow Band and Linear Ramp Filters
As part of the WFPC2 close-out calibrations, we examine the stability of the bandwidths of the narrow band and linear ramp filters. We measure the FWHM of the spots produced by VISFLAT exposures using linear ramp filters crossed with narrow band filters. We do this for eight different pairings of narrow band and linear ramp filters. We then compare results from 1995 and 2008, and find negligibl...
متن کاملWavelength Stability of the WFPC2 Narrow Band and Linear Ramp Filters
As part of the WFPC2 close-out calibrations, we test for long-term changes in the wavelength calibration of the narrow band and linear ramp filters. Relative wavelength measurements are made by crossing each narrow band filter with one of the linear ramp filters and taking a VISFLAT, and then noting the position of the resulting bright spot in the field of view. We test the stability of the cen...
متن کاملWFPC2 Photometric Calibration
The updated absolute photometric calibration for WFPC2 yields typical uncertainties for bright sources below 2% for the photometric filter set and of about 3% for other filters between 400 and 800 nm. We present a quantitative characterization of some well-known WFPC2 non-linearities, the CTE error and the long vs. short anomaly, which allows a better estimate of their possible impact under a v...
متن کاملWFPC2 Calibration for Emission Line Images
Formulae for the flux calibration of WFPC2 emission lines are presented. The photometric information given in the header is not adequate, and does not consider the contamination due to neighbouring emission lines in the filter passband or by the continuum. The formulae were originally calibrated using groundbased images of the Orion Nebula. The photometric accuracy of the flux calibration proce...
متن کاملWFPC2 Flatfields with Reduced Noise and an Anomaly of Filter FQCH4N-D
The transmission of the filter FQCH4N-D varies by 20 percent across the filter while the mean wavelength shifts by 3 nm. For objects with a flat spectrum across the main bandpass (889–897 nm), the flatfielding removes the spatial variations except for the outer corner, for which we give the necessary photometric correction. On the other hand, for objects with steep spectral features within the ...
