This directory contains log files produced by SDSS telescope control systems, imaging camera and spectroscopic instrument.
To jump to links to the individual MJD directories, click here.
These data should be regarded as the source material for metadata used by the SDSS imaging and spectroscopic processing pipeleines (photoop and idlspec2d). However, these data are not the actual metadata used those pipelines. That metadata can be found in the photolog and speclog products, respectively. In other words, the photolog and speclog products are the curated versions of the raw data found here.
During the summer of 2015, as part of the transition from SDSS-III to SDSS-IV, astrolog data was transferred from APO to long-term archiving. However, there were already two other versions of these data extant. Here is a brief description of the three versions:
In addition there is some duplication of files with the oplogs data. These files are left alone.
The MJD directories in the same directory as this file contain a deduplicated sample from these sources. The deduplication followed the procedure outlined below.
The removal of duplicate files followed this procedure. For each MJD directory in each of the three sources listed above:
The code that implements this procedure is in python/deduplicate.py in the sas product.
The log showing the files and directories that were moved is here.
After deduplication, the remaining contents of apo_engineering and apo_staging were mothballed:
The following subdirectories were discovered:
The original README file in this directory is preserved below.
51615/plPlugMapM-0323-51612-01.par
Changed the SPECTROPHOTO_STD stars to those suggested by Hogg
51579/plPlugMapM-0318-51578-01.par
Changed the SPECTROPHOTO_STD stars to the following two:
FIBERID=255 RA=132.55750 DEC=11.356539
FIBERID=558 RA=133.01796 DEC=11.911908a
These changes were made by changing the u,g,i,z magnitudes such that these
stars will be selected.
The existing SPECTROPHOTO_STD objects were renamed to UNKNOWN.
Are the SKY fibers really sky??

On 13 Nov 02, I have done an rsync from sdsshost.apo:/astrolog
for MJD = [52510, 52592] (today). This is to get the imaging log files
for these dates, which were not copied by SOS.

--> Run /scr0/data/astrolog/rsync.13nov02 !!!???
On 13 Nov 02, I have copied the Fermi golden directories at Princeton
for MJD 50991 to 51259 (pre-spectroscopy days, which started on 51433).
Since I'm using the Princeton version, this includes the Finkbeiner-edits
to the idFrameLog files for the Orion scans.
We still need the idAstroline files for runs 745->756,
corresponding to MJD 51257->51259, which aren't even in the Fermi
golden directory.
The following directories existed in the golden directory,
but not in astrolog. I'll copy from the golden directory ???
