Raw data files
wxxxxxxxx_d0f .d0h/.d0d _d0f.fits It contains the WFPC image data with the readout from each CCD detector in each group. Hence from 1 to 4 groups may be present. Keywords in the header are used to select the various processing steps and to specify the names of the necessary reference files. 5 MB W1MN0307T_D0F
wxxxxxxxx_q0f .q0h/.q0d _q0f.fits The DQF must consist of short integers and have the same dimensions and number of groups as the Science Image file. Each pixel indicates the quality of the corresponding pixel in the Science Image file. Zero valued pixels indicate "good" pixels in the Science Image file and nonzero valued pixels flag various problems or potential problems with their corresponding pixels. 5 MB W1MN0307T_Q0F
wxxxxxxxx_x0f .x0h/.x0d _x0f.fits It contains the two "engineering" column and, for FULL mode, the 12 columns of overclocked pixels. It has the same number of groups as the Science Image file. 100 kB W1MN0307T_X0F
wxxxxxxxx_q1f .q1h/.q1d _q1f.fits The EED quality file must consist of short integers and have the same dimensions and number of groups as the EED file. Each pixel indicates the quality of the corresponding pixel in the EED file. Zero valued pixels are "good" pixels in the EED file and nonzero valued pixels flag various problems or potential problems with their corresponding pixels. 100 kB W1MN0307T_Q1F
wxxxxxxxx_shf .shh/.shd _shf.fits Telemetry values and spacecraft operation data. 30 kB W1MN0307T_SHF
wxxxxxxxx_pdq .pdq _pdq.fits Text file containing jitter statistics and other data quality information 20 kB W1MN0307T_PDQ
Calibrated data files
wxxxxxxxx_c0f .c0h/.c0d _c0f.fits It is in REAL format (although an option is available to provide FITS-like scaling to SHORT or LONG integers). Extreme values resulting from input data values outside of the range of the WF/PC-II AtoD converter (0 to 4095) are edited to limit the range of values in the output image. These pixels are set to the value of the keyword RSDPFILL and flagged in the DQF. 10 MB W1MN0307T_C0F
wxxxxxxxx_c1f .c1h/.c1d _c1f.fits The DQF for the Calibrated Science Image file follows the same conventions as the Science Image Data Quality file. This contains the result of bitwise ORing, the input DQF, and all DQFs associated with reference files used in the processing of the Science Image file. 5 MB W1MN0307T_C1F
wxxxxxxxx_c2f .c2h/.c2d _c2f.fits Histogram of science data pixel values. 5 MB W1MN0307T_C2F
wxxxxxxxx_trl .trl _trl.fits Trailer file 10-30 kB W1MN0307T_TRL
