Since tower masking is  done with the same inputs in database by setting time dep. correction values negative  for bad towers, 1) how towers are masked 1) how time dep. correction files are written, 3) how they are loaded in datbase, and 4)  how the information can be fetched from database are explained below .

• How towers are maseked

The xml file(Sub_L.xml) take run by run jobs and list towers for each run.

Channels are populated in different ADC & energy thresholds : 
/star/data01/pwg/mriganka/fms2015/jetData2011/new/hotCh/StRoot/StFmsHitMaker/StFmsHitMaker.cxx
SET-1
            h0->Fill(((d-8)*1000)+c);
            hh0->Fill(((d-8)*1000)+c,adc);
SET-2
            if(adc>10){
            h10->Fill(((d-8)*1000)+c);
            hh10->Fill(((d-8)*1000)+c,adc);
            }
SET-3
            if(adc>50){
            h50->Fill(((d-8)*1000)+c);
            hh50->Fill(((d-8)*1000)+c,adc);
            }
SET-4
            if(adc>100){
            h100->Fill(((d-8)*1000)+c);
            hh100->Fill(((d-8)*1000)+c,adc);
            }
SET-5
           he0->Fill(((d-8)*1000)+c);
            hhe0->Fill(((d-8)*1000)+c,e);
SET-6
           if(e>1){
            he1->Fill(((d-8)*1000)+c);
            hhe1->Fill(((d-8)*1000)+c,e);
            }
SET-7
           if(e>10){
            he10->Fill(((d-8)*1000)+c);
            hhe10->Fill(((d-8)*1000)+c,e);
            }
SET-8
            if(e>20){
            he20->Fill(((d-8)*1000)+c);
            hhe20->Fill(((d-8)*1000)+c,e);
            }

 
For each SET 4 top bincontent towers are being selected. A tower is being marked to be masked if belong in the 4*8 set. There are several common.
Generally the number is ,ess than 20.

Writes hot channels run by run  in "txt" directory with gif files in "gif"  : the inputs from the txt file will be used when writing in database. Each *.txt file for one run.
/star/data01/pwg/mriganka/fms2015/jetData2011/new/hotCh/test/run.C. The information from *.txt files will be used when database would be written run by run.

• How time dependent files are prepared

Basic concept is to mark channels for which correction is significnat. It is such that with minum inputs in database, we can perfrom time dep. correction without overloading the database.
Some details are written  here : https://drupal.star.bnl.gov/STAR/blog/mriganka/fms-led-time

In starver SL14i from PSU TimeDepCorr.root was locally  generated.  We are listing the channels to be corrected for each time slot. Each time slot is a section of 10k data. Since the evnets nummber is unique in trigger file and microDst files there is one to one relation with time slots and MuDst event numbers.

/star/data01/pwg/mriganka/fms2015/jetData2011/old/led/test1

running the macro txt1/read.C lists : Run Number       #Events(fms_st)    time-slots    Entries in Database

/star/data02/pwg/mriganka/root12fms/fmstxt/RunDep.root (Steven Heppelmann run11 list)

fprintf(f,"%10d %6d  %6d\n", mCurrentRunNumber, nEnt, timeSlot);
fprintf(f," %hu %hu %lu  %f \n", detectorId, ch, 999000000, 1); -- for last time slot
fprintf(f," %hu %hu %lu  %f \n", detectorId, ch, endEvent, corr); -- for time slots where chages are required

• Writing in database

 In couple with time dependent masked tower inputs are set into database (time dep. correction values are set to negative for mased towers).
/star/data01/pwg/mriganka/fms2015/jetData2011/old/led/test1/AKIO/writeFMSAll.C
Masked tower inputs : sprintf(fileTowers,"/star/data01/pwg/mriganka/fms2015/jetData2011/new/hotCh/test/txt/tower_rejected_%d.txt",iR);
Time dep. correction inputs : sprintf(fileTimeDep,"txt/f_%d.txt",iR);

• Reading after implementation of time dep. and hot tower rejection in StFmsHitMaker

The macro is running for Jet recontruction with FMS towers using tower masking and tome dep. correction.
/star/data01/pwg/mriganka/fms2015/jetData2011/new/hotCh/t/mod/RunJetFinder2009pro.C
Two switches are set in StFmsHitMaker
fmshitMk->SetTimeDepCorr(1);   // does time dep, correction : default is "0"
fmshitMk->SetTowerRej (default = 1) // how tower rejection
