PR #156 merged the first version of the code which connects mock catalogs to spectra (and the corresponding target and truth catalogs). However, there were a number of outstanding issues (in no parti…

In the pre-2% data challenge spectra redrock was failing dramatically on QSOs, which was eventually tracked down to an issue with the templates. Cell [9] of this notebook demonstrates the issue:
htt…

The results for eta should be the same across forests since it only depends on the error of precision
calibration at a given wavelength.
In other words, eta is a function of lambdaOBS not of lambdaR…

@andreufont noticed that quasars returned by desisim.templates.make_templates are not at the specified redshift. I looked into it and found that the problem comes from desisim.qso_template.desi_qso_te…

When loading a DLASurvey from literature with the 'stat' sample e.g.,
`xq100=DLASurvey.load_XQ100(sample='stat')`
The output will show that _no_ DLAs were found:
``
I think the issue is in DLASurv…

First identified in #234: when we add Lyman-alpha absorption to QSO templates, they often fail the targeting color cuts for QSOs with 3.1 < z < 3.7 . I suspect that we are double applying LyA mean ab…

I run do_deltas over 209 QSOs (plates 5400 and 5401) with MacOS and Linux. both are using anaconda and minuit 1.2. The results obtained for the continuum are significantly different, see below:
Mac…

I am having problems trying to use an external keyer or straight key. The internal keyer works great. The start of the character is clipped each time the mcHF goes to TX mode. If the txrx delay is inc…

When doing the cross-correlation,
we loose all the SDSS-I and SDSS-II QSO with the cut THING_ID

Just for information and to avoid the confusion in operation (D2.5.98):
I am using a `CW display=SHIFT`
With this setting I get the proper frequency display for CW and SSB.
An example for CW:
