| """ |
| 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 |
