2.7	STIS Paper Products

The calibration pipeline formerly produced paper products that summarized the data obtained. Archival observers can recreate these paper products by retrieving all of the science and jitter data for a particular observation (see Chapter 1 of the Introduction to the HST Data Handbooks) and using the STSDAS pp_dads task (at the IRAF prompt type: pp_dads *.fits). It is recommended the device parameter of the pp_dads task be left at its default value of psi_land. Note that the output file may be created in the /tmp directory on some unix systems. Although this output file is in postscript, the name of the file may not end in “.ps”. For example, in one test case the file name was psk9060a.

STIS paper products are designed to summarize a set of exposures for a single visit. A given page in the STIS paper product falls into one of two categories: a visit-level page or an exposure-level page. Below, we list the individual pages contained in the STIS paper products; Figure 2.7 through Figure 2.10 provide samples of the paper products pages. Users are encouraged to read ISR STIS 97-11, which provides more details about the STIS paper products.

Visit-Level Pages

•	Cover Page: A cover page containing the proposal ID, the visit number, the PI’s name, and the proposal title.

•	Explanatory Notes (Figure 2.7): A set of notes explaining the paper products and the information they contain.

•	Target List (Figure 2.8): A table listing the targets for a given set of observations.

•	Observation list: A table recapping the proposal information for each exposure for the set of observations being summarized, including three processing and data quality flags, corresponding to OK, not OK, and unknown status.

•	Optional Parameters: A table listing the proposal-level optional parameters for the set of observations being summarized.

•	Statistics: A table of simple statistics for the set of observations being summarized to allow for a quick comparison among observations.

Exposure-Level Pages

•

Exposure Plots: This is a graphical representation of the data contained in each exposure. Plots are specific to a particular instrument configuration and observing mode. In some cases, more than one plot is produced. The types of exposure plots are: ACQ image plot (Figure 2.9), ACQ/PEAK image plot, image plot (Figure 2.10), rectified two-dimensional spectral image plot, one-dimensional extracted spectrum plot, and time-series plot.

•	Data Quality Summary: Consists of a comprehensive summary of the spacecraft performance, pipeline processing status, and calibration data quality for each exposure.

•	Calibration Reference File Summary: A summary of the calibration processing switches and reference files used to process each exposure.
