Extracts the light curves of ("monitors") all time-variable objects of cosmological interest. The basic concept is a general purpose light curve extraction tool, that can be sub-classed to specialize in supernova monitoring or lensed quasar monitoring. In an ideal world, this code would merely take care of the book-keeping involved in assembling light curves in the appropriate format for modeling codes like SNCosmo and SLTimer by simply querying the various DM Level 2 databases. However, we are aware of the possibility that we may need to implement multi-object extended MultiFit (a.k.a. "SuperFit") routines into the Monitor, if the Level 2 light curves do not provide sufficient accuracy. (This is a particular worry for the SLMonitor, which will need to deal with highly blended objects). The Monitor is therefore being developed as "Level 3" code, following DM standards and module structure.
From bash:
$ source setup/setup.sh
$ nosetests
or use the c-shell alternative. The Monitor uses some DM stack code, notably the Butler; see the installation notes for help getting set up.
#####Setting up ssh tunnel for database access:
In order to produce light curves with output from the Twinkles project one needs to be able to access the SQL database where DM processed output is stored. To do that one needs to setup an ssh tunnel for access. We use the same tools as the connection to the UW LSST CATSIM Database with instructions here. Follow the step at the beginning to install the necessary tools and then replace step 1 code with the following command line entry with your NERSC username in the proper place:
ssh -L 3307:scidb1.nersc.gov:3306 [email protected]
Do not worry about step 2 and continue to step 3 where you are instructed to create a db-auth.paf file, but replace the code on the website with the following parameters:
database: {
authInfo: {
host: '127.0.0.1'
port: 3307
user: $db_username
password: $db_password
}
}
If you do not have the $db_username or $db_password and are interested in access please contact a member of the Monitor team for more information.
