This page contains astronomy-related programs I've written over the years, mostly within the Interactive Reduction and Analysis Facility (IRAF) package.
PHIIRS -- Pat Hall's Infrared Imaging Reduction Software
This is a suite of IRAF tasks for the reduction of infrared imaging data. It was spawned from original tasks by Doug Williams & Anne Turner and including many cannibalized parts from the DIMSUM package of Eisenhardt et al. which, like PHIIRS, is also available from the IRAF contributed software web site.
PHIIRS 2.12 for IRAF Version 2.12 (030626) You may also need the PHAT package, or at least the tasks ptv.cl and iteravg.cl (along with iteravg.par).- PHIIRS 2.11.2 for IRAF Version 2.11 + FITS kernel (010108) plus tasks with minor bug fixes superseding the tasks found in the tar file (last updated 010108). Now including "dophiirs.cl" script task. Read "phiirs.hlp" and "doc/dophiirs.hlp" for an introduction and overview. Other changes from v.2.11 (besides inevitable bug fixes): renamed task "irflat2.cl" to "domeflat.cl"; added tasks "cfhtfirst.cl", "onisfirst.cl", & "piscesfirst.cl" for use with particular telescope/ instrument combinations; better "irshift.cl", "qkflat.cl" & "qksky.cl"; "nshift.cl" task added for finding offsets for N images or image sets overlapping a central image, and "onis6pt.cl" & "onis3ew.cl" included as examples of how to build a large mosaic from individual image sets; and streamlined tasks for faster reduction of large IR arrays (e.g. iterstat can be run for single parameters only; irshift includes an imsection parameter to avoid displaying every image; & minv is faster).
- PHIIRS 2.11 for IRAF Version 2.11 + FITS kernel (980805). Default image extension is now assumed to be "fits" instead of "imh".
- PHIIRS 2.10 for IRAF V2.10 (980313). Tasks are now available for complete reduction from raw data to images suitable for input to FOCAS or other object detection software. NOTE that several perl scripts (included with the package) are used for image coaddition if the CTIO package is unavailable. Several awk scripts are also used for photometric scaling tasks. Read "phiirs.hlp" for an introduction. To install, enter the proper pathnames in "phiirs.cl" and "phiirs.hd", load the softools IRAF package, and type "mkhelpdb root.hd helpdb.mip", deleting the old helpdb.mip if necessary. See "sample.loginuser.cl" for how to include the package in your default IRAF startup.
This version of PHIIRS has been updated to handle the DATE-OBS keyword in both the "old" format of "dd/mm/yy" and the new millenial format "yyyy-mm-dd" (this affects the tasks first.cl, irimfirst.cl, and irtffirst.cl only). Currently I believe the IRAF astutil.setairmass task only accepts the old format, but presumably any update to it will be backwards compatible. - Other infrared reduction software packages: dimsum | eclipse | cirred | cirdr | IRDR
PHAT -- Pat Hall's Add-on Tasks
- PHAT 2.11.1 for IRAF Version 2.11 + FITS kernel (990519). Many tasks require the PHIIRS package to run.
- Version 2.10 for IRAF V2.10 (980317). This is my compilation of personal miscellaneous add-on IRAF tasks and their help files, including some tasks for defringing and coadding optical CCD data. The entire package is available as a gzip-compressed tarfile in either a standalone version (128k), or a version supplementary to PHIIRS (79k). This latter version requires the PHIIRS package to run. To install, enter the proper pathnames in "phat.cl" and "phat.hd", load the softools IRAF package, and type "mkhelpdb root.hd helpdb.mip", deleting the old helpdb.mip if necessary.
PHIST -- Pat Hall's Interactive Sloan Tasks
- Version 2: 011207. This is a collection of IRAF tasks for looking at SDSS spectra.
PHUC -- Pat Hall's Utility Compilation
- Version 0: 990513. This is a disorganized collection of tasks to take coadded images of the same field in different filters, run FOCAS on them, and organize the output. See the README_PHUC file for details and outline.
PHXS -- Pat Hall's X-ray Software
- Version 1: 960626. These (mostly batch) tasks were designed for searching for extended X-ray emission around unresolved point sources (clusters around quasars). Read "phxs.hlp" for an introduction and detailed guide. The entire package is available as a gzip-compressed tarfile (~100k). To install, enter the proper pathnames in "phxs.cl" and "phxs.hd", load the softools IRAF package, and type "mkhelpdb root.hd helpdb.mip", deleting the old helpdb.mip if necessary.
