Known Problems & Limitations¶

expects FeAr and (simulataneous) HeNeAr arcs in the 0.5 arcsec slit
any absorption features in the “featureless” telluric calibration will become emission features in the corrected spectrum
fluxing is not correcting for extinction?
only one object can be extracted from a given image
some fluxing weirdness at the shortest blue wavelengths
joining red and blue sides with combine_sides often introduces artifacts

Todos¶

fluxing should correct for extinction
improve telluric correction defaults
improve robustness of joining red and blue sides (bad fluxing kills it)
wrapper for single extract-combine-plot run
script to “undo” various parts of the analysis? eg, start from scratch w/ standards
Brani suggests only using arcs taken in a single batch–need to adjust code logic
automate wavelength coordinate assignment for autoidentify?
calculate gain & readnoise from cal files
set fwhm_arc correctly (currently only uses a default)
write auto-joiner to speed joining and coaddition
write a log file to record processing steps taken
add pipeline version and reducer information to output headers

(ongoing)

Bug fixes:

allow check_gratings_angles to handle decimal ANGLE keywords
handle bug where flatcombine expected multiextension FITS
Provide smoother handling if create_arc_dome(side=’both’) is called when data from only one side are present
