""" |
|
Used to pull the list of observations that fit our filter criteria from |
|
online Hubble archives. See all filter details in the function call below. |
|
|
|
sci_spec_1234='F606W,F606W;*,*;F606W,*;F606W;*' |
|
|
|
We are only pulling observations which have used the F606W filter, which is one of the most commonly used ACS filters. |
|
We need the regex strings because observations that used multiple filters will include all filters in a list. |
|
Documented at https://etc.stsci.edu/etcstatic/users_guide/appendix_b_acs.html |
|
|
|
sci_aec='S' |
|
|
|
This value denotes that we are searching only for science observations, not observations that were done in order to |
|
calibrate various parts of the instrument or imaging process. |
|
|
|
sci_instrume='acs' |
|
sci_instrument_config='ACS/WFC' |
|
|
|
Here, we define that we want data from the ACS/WFC instrument. |
|
|
|
sci_expflag='NORMAL' |
|
|
|
This is a quality flag, ensuring that no quality issues were flagged for this observation. |
|
|
|
sci_actual_duration='>300' |
|
|
|
We require the minimum total observation duration to be at least 300 seconds, to remove any faulty observations |
|
that may have ended after a short period of time and to further narrow the distribution of data away from edge cases. |
|
|
|
sci_aper_1234='WFC,WFC1,WFC2,WFCENTER' |
|
|
|
We require that the aperture be one of the standard apertures, documented at |
|
https://hst-docs.stsci.edu/acsihb/chapter-7-observing-techniques/7-7-acs-apertures |
