A list of known issues, features and bugs in SciServer software, webapps, and APIs.

Altair Update 3 (v1.8.1)

CAS Upload to SAS does not work for DR13 Spectra

Issue

SkyServer query output buttons “Upload list of fields (or spectra) to SAS” do not work for DR13. You will be taken to the DR12 SAS instead for both images and spectra. Although there’s no new imaging data in DR13, there are spectra in DR13 that currently cannot be retrieved by uploading CAS query results to the SAS.

Workaround

There is currently no workaround. This bug is expected to be fixed in the next patch.

Altair Update 2 (v1.8.0)

Can’t install Astroquery or other Python 2 modules in Compute Jupyter Notebook with Pip.

Issue

The Compute kernel runs under Python 3. Pip executes shell commands within the Python 3 environment, even if you are using the Python 2 kernel. All libraries installed with “!pip install” are installed in the Python 3 environment, not Python 2. Python 2 modules and libraries may fail to install.

Workaround

Although users may update and change the Docker-Python configuration in Compute, we do not generally offer support for issues that arise from attempting to install non-standard libraries. We may include requested libraries in future SciServer updates and releases.

As a workaround, we suggest that you use “conda install” instead of “pip install”, because it lets you specify the environment for package installation.

Example

You can install astroquery for Python 2 from your Jupyter notebook like this:

!conda install -y -n py27 -c astropy astroquery

Then restart the kernel (see Help in the Compute Dashboard for more info on how to start and stop the kernel.

Altair Update 1 (v1.7.7)

SDSS Command Line Query Tool (sqlcl) uses outdated x_sql.aspx link

Issue

The SDSS Command Line Query Tool (sqlcl) contains a hardcoded link to x_sql.aspx, which is not part of the current SkyServer API.

Workaround

The SDSS Command Line Query Tool (sqlcl) is no longer officially supported by SDSS. A new python-based command line tool is under development but is not yet available.

Users who wish to continue to use sqlcl should manually update the sqlcl code to replace “http://skyserver.sdss3.org/public/en/tools/search/x_sql.aspx” with http://skyserver.sdss.org/SkyserverWS/dr12/SearchTools/SqlSearch.

Example

http://skyserver.sdss.org/dr12/en/tools/search/x_results.aspx?searchtool=SQL&TaskName=Skyserver.Search.SQL&syntax=NoSyntax&ReturnHtml=true&cmd=SELECT+TOP+10+p.objid+FROM+PhotoObj+AS+p+JOIN+SpecObj+AS+s+ON+s.bestobjid+%3D+p.objid%0D%0A&format=html&TableName=

x_sql.aspx does not exist

Issue

Going to the URL skyserver.sdss.org/dr12/en/tools/search/x_sql.aspx results in:

An error has occurred in Skyserver
The file '/dr12/en/tools/search/x_sql.aspx' does not exist.

Resolution

Some SkyServer services have been updated to use REST. The new URL is

http://skyserver.sdss.org/SkyserverWS/dr12/SearchTools/SqlSearch

Cannot log in to Login Portal with CasJobs username & password

Issue

Attempting to log into SciServer Login Portal with CasJobs credentials fails with error

“Authentication failed”

Resolution

Existing CasJobs users must migrate their accounts to SciServer on the Login Portal’s Register page using their existing CasJobs username and password.

After registering, their authentication details will be in the system, and they can login via the Login Portal.

Forgotten CasJobs username or password

Issue

CasJobs users who have forgotten their CasJobs username or password cannot register on the SciServer Login Portal.

Resolution

Forgotten Password: Email the SciServer Help Desk from your CasJobs email address and request that your CasJobs password be reset. Please supply your CasJobs ID and email address.
Forgotten Username: Email the SciServer Help Desk from your CasJobs email address and ask for your username.

Altair Release (v1.7.2)

SOAP web services are no longer supported

Issue

SOAP web services are no longer supported. New web services have been implemented with a REST API.

Workaround

The REST API for CasJobs is described here.
