How to read Cache file and Time Series Data
Cache file direction
- In k1det1
[detchar@k1det1~]$ cd /home/detchar/Cache [detchar@k1det1 Cache]$ ls K1-Cache.cache mkCache.py nohup.out
- In seikai, only the ikagra data cache is stored.
[user@seikai~]$ cd /home/detchar/Cache/ikagra_cache/ [user@seikai Cache]$ ls ikagra_cachefile.cache mkCache.py
Read Cache file
1 from glue.lal import Cache
2
3 gwf_cache = '/home/detchar/Cache/K1-Cache.cache' # Specify 'Cache file path' here
4
5 with open(gwf_cache, 'r') as fobj: # Read the cache file using glue.lal
6 cache = Cache.fromfile(fobj)
7
8 type(cache) # type of cache is glue.lal.Cache
9 glue.lal.Cache
10
11 cache # Contants of cache
12 [<glue.lal.CacheEntry at 0x7f8004092050>,
13 <glue.lal.CacheEntry at 0x7f8004092110>,
14 .
15 .
16 .
17 <glue.lal.CacheEntry at 0x7f7fce88a850>,
18 <glue.lal.CacheEntry at 0x7f7fce88a910>,
19 ...]
Read Time Series Data
Reference Link : https://gwpy.github.io/docs/stable/api/gwpy.timeseries.TimeSeries.html#gwpy.timeseries.TimeSeries
1 from gwpy.timeseries import TimeSeries
2
3 ch = 'K1:LSC-MICH_CTRL_CAL_OUT_DQ' # Specify 'Channel Name' by string type
4 gst = 1199756064.0 # Specify GPS start time by float or integer type
5 get = 1199756064.0 + 600 # Specify GPS end time by float or integer type
6
7 data = TimeSeries.read(cache, ch , gst, get, format='lalframe')
