2. Filter & explore results#
The querying functions presented in the previous section return a PANDAS DataFrame that can be used to further narrow down your search. This section presents some examples of how you can further filter and explore the results of your queries:
Load libraries & create a query
To explore these options, we will first query the archive using one of the methods presented in the previous section and use the results in the remainder of this tutorial.
[1]:
import alminer
observations = alminer.keysearch({'science_keyword':['Galaxy chemistry']},
print_targets=False)
================================
alminer.keysearch results
================================
--------------------------------
Number of projects = 48
Number of observations = 341
Number of unique subbands = 1166
Total number of subbands = 1368
Total number of targets with ALMA data = 64
--------------------------------
2.1 Explore results#
You can simply display the DataFrame table returned by the query functions using the name you gave it (in this case observations), but often there are limits to how many rows and columns are presented. With the alminer.explore function, you can control whether or not you want to display all rows (allrows=True/False) and/or all columns (allcols=True/False). By default, only the 18 most useful columns are shown and the number of rows is truncated.
Example 2.1.1: View the queried observations as a table (shortened)#

alminer.explore(observations, allcols=True, allrows=False)
# you can also set allrows=True to see all rows in the table
# but this may be slow for very large queries

2.2 Summarize results#
The alminer.summary function will print a summary of the observations. This is done by default when the query is run, but it’s a useful function if the results are filtered further, as shown in the next section.
Example 2.2.1: print the summary of a given query result, including a list of unique ALMA target names#

Example 2.2.2: print the summary of a given query result WITHOUT the list of target names#
For big tables, it is useful to avoid printing the list of target names in the summary. This can be done by setting print_targets=False.
[5]:
alminer.summary(observations, print_targets=False)
--------------------------------
Number of projects = 48
Number of observations = 341
Number of unique subbands = 1166
Total number of subbands = 1368
Total number of targets with ALMA data = 64
--------------------------------
2.3 Filter results#
The search results can be further narrowed down by using PANDAS DataFrame functions. See also this introduction to data structures. For example, you can use your_query.columns to get a list of all columns in the DataFrame.
To get the description and units of any column use the function alminer.get_info(‘column_name’) where column_name is the name of the column.
Example 2.3.1: simple selection - observations with angular resolutions < 0.5”#
Let’s first check what the description and units of ang_res_arcsec column are:
[6]:
alminer.get_info('ang_res_arcsec')
--------------------------------
Column: ang_res_arcsec
--------------------------------
Description: typical spatial resolution
Units: arcsec
--------------------------------
Now we can do the some further filtering, say to only keep observations with angular resolutions < 0.5”:
[7]:
selected = observations[observations['ang_res_arcsec'] < 0.5]
and print the summary:
[8]:
alminer.summary(selected, print_targets=False)
--------------------------------
Number of projects = 23
Number of observations = 107
Number of unique subbands = 313
Total number of subbands = 427
Total number of targets with ALMA data = 41
--------------------------------
Example 2.3.2: multiple selections - observations with angular resolution < 0.5” & velocity resolution < 1 km/s#
[9]:
selected = observations[(observations['ang_res_arcsec'] < 0.5) &
(observations['vel_res_kms'] < 1.0)]
alminer.summary(selected, print_targets=False)
--------------------------------
Number of projects = 10
Number of observations = 50
Number of unique subbands = 78
Total number of subbands = 120
Total number of targets with ALMA data = 27
--------------------------------
Example 2.3.3: observations containing a given frequency#
[10]:
freq = 220.5
selected = observations[(observations["min_freq_GHz"] < freq) &
(observations["max_freq_GHz"] > freq)]
alminer.summary(selected, print_targets=False)
--------------------------------
Number of projects = 6
Number of observations = 7
Number of unique subbands = 7
Total number of subbands = 7
Total number of targets with ALMA data = 5
--------------------------------
2.4 Line coverage#
An alternative to the last example in the previous section is the alminer.line_coverage function which determines how many targets were observed at a given frequency with the option to include a redshift for the line of interest to be taken into account. Some notes: * Line frequencies should be given in GHz * Redshift is by default assumed to be 0 * The line_name keyword is the user’s defined name for the frquency provided
Example 2.4.1: search whether a given frequency is covered in the observations#
[11]:
myline_obs = alminer.line_coverage(observations,
line_freq=220.5,
z=0,
line_name="My favourite line",
print_targets=True)
--------------------------------
Summary of 'My favourite line' observations at 220.5 GHz
--------------------------------
Number of projects = 6
Number of observations = 7
Number of unique subbands = 7
Total number of subbands = 7
5 target(s) with ALMA data = ['Arp220', 'ngc_3256', 'IRAS_13120-5453', 'ngc253', 'NGC_253']
--------------------------------
Example 2.4.2: search whether a given frequency is observed for a target at a given redshift#
[12]:
myline_obs = alminer.line_coverage(observations,
line_freq=400.0,
z=0.5,
line_name="My favourite line",
print_targets=True)
--------------------------------
Summary of 'My favourite line' observations at 400.0 GHz (266.667 GHz at z=0.5)
--------------------------------
Number of projects = 8
Number of observations = 10
Number of unique subbands = 11
Total number of subbands = 11
6 target(s) with ALMA data = ['ngc4418', 'Arp220', 'ngc_3256', 'circinus', 'ngc4945', 'ngc253']
--------------------------------
2.5 Coverage of CO, 13CO, and C18O lines#
The alminer.CO_lines function determines how many CO, 13CO, and C18O lines were observed in the provided DataFrame and returns a DataFrame containing all observations of these transitions.
Example 2.5.1: search whether any CO, 13CO, and C18O lines were observed in the query results#
