11. Solutions to exercises

11.1. Solutions to the Local calibration manager exercises

11.1.1. Solution to Exercise - Caldb 1 

The dragonrc file should look like this:

[calibs]
#databases = <where_the_data_package_is>/niriimg_tutorial/playground/cal_manager.db get
databases = <where_the_data_package_is>/niriimg_tutorial/cal_manager.db get

ls <where_the_data_package_is>/niriimg_tutorial should show a file called cal_manager.db. And

caldb config

Using configuration files: ('~/.dragons/dragonsrc',)

/Users/klabrie/data/tutorials/niriimg_tutorial/cal_manager.db
  Type:  LocalDB
  Get:   True
  Store: False


Database file: /Users/klabrie/data/tutorials/niriimg_tutorial/cal_manager.db

The calibration dbs are all local, meaning that remote calibrations will not be downloaded

11.1.2. Solution to Exercise - Caldb 2 

It is important do to successfully complete Exercise - Caldb 1 before attempting Exercise 2.

First confirm that the new calibration manager, the one niriimg_tutorial is active.

caldb config

Using configuration files: ('~/.dragons/dragonsrc',)

/Users/klabrie/data/tutorials/niriimg_tutorial/cal_manager.db
  Type:  LocalDB
  Get:   True
  Store: False


Database file: /Users/klabrie/data/tutorials/niriimg_tutorial/cal_manager.db

The calibration dbs are all local, meaning that remote calibrations will not be downloaded

Question 1

caldb add N20160102S0373_flat.fits

Question 2

caldb list

N20160102S0373_flat.fits       /data/workspace/niriimg_tutorial/playground

Question 3

Edit dragonsrc. Comment out the niriimg_tutorial path and uncomment the playground path.

[calibs]
databases = <where_the_data_package_is>/niriimg_tutorial/playground/cal_manager.db get
#databases = <where_the_data_package_is>/niriimg_tutorial/cal_manager.db get

Confirm activation with caldb config.

11.2. Solutions to the `reduce` exercises

11.2.1. Solution to Exercise - “reduce” 1 

reduce @flats.lis -p normalizeFlat:scale=mean --suffix _exercise1

11.2.2. Solution to Exercise - “reduce” 2 

reduce @target.lis -r makeSkyFlat --suffix _skyflat

11.2.3. Solution to Exercise - “reduce” 3 

While it is not recommended to use a processed dark of the wrong exposure, here is how you would force DRAGONS to use the science’s master dark on the flux standard from the demo.

reduce @stdstar.lis --user_cal processed_dark:N20160102S0423_dark.fits
