SVM: Add SVM drizzle parameters for N=1 (ACS & WFC3) #1261

Closed stscijgbot-hstdp closed 2 years ago

stscijgbot-hstdp commented 2 years ago

Issue HLA-714 was created on JIRA by Jennifer Mack:

Add new N=1 JSON files for ACS and WFC3 (attached) 

Parameters for single frames: skysub=False, driz_separate=False, median=False, blot=False, driz_cr=False, final_bits=65535

Replace existing JSON files for N=2, N=4, and N=6  (attached)

Set driz_sep_kernel=square, Set combine_type=minmed for N=2, N=4 and median for N=6.

Comment by Jennifer Mack on JIRA:

Roberto Avila  Can you verify these new N=1 JSON files for ACS/WFC and ACS/HRC?   Also, for SBC, I think the N=2 settings work for N=1, but I defer to you.

For WFC3/UVIS, the settings for N=1 are the same for pre-2012 and post-2012 so I only attach one file.

Comment by Roberto Avila on JIRA:

the ACS/WFC n=1 files looks good.

For the other detectors, I have a question about the plate scale.  I seem to remember that the HRC and SBC products are currently drizzled to a plate scale of 0.025"/pix. I think the PAMs correct to that. Should we keep that same convention here? If we do we have to update all the json files for SBC and HRC.

WFC3 updates for SVM processing:

Comment by Roberto Avila on JIRA:

ACS updates for SVM. 

I'm including HRC and SBC parameters so that they are there in case we want to start drizzling those at some point in the future.

Comment by Jennifer Mack on JIRA:

I removed ACS duplicates.  Some files will need to be renamed to remove the '-1' suffix to match the original naming convention.

Comment by Roberto Avila on JIRA:

Uploaded two new files, acs_sbcastrodrizzle blue_n*.json

These are for the F115LP and F122M filters ONLY. The background sky in these two filters is substantial and therefore the sky subtraction step needs to be turned on.

Comment by Roberto Avila on JIRA:

Also uploaded new acs_sbc_astrodrizzle_any_total.json file. The one in the repo was a a copy of the WFC version and the parameter settings were not adequate for SBC.
